Re: [Repeater-Builder] Coax length, etc.
Hi Kevin: Regarding temperature, our club has a site, no A/C or heat, where temperatures inside the shelter can get below +20 deg F in winter, and well over 130 deg F in the summer heat. I can't imagine filter tuning not changing under such conditions, Invar or not. I can see over time where tuning might walk off the reservation. But I bow to your greater experience with cavity duplexers. Another chance? Which part, erroneous readings, don't directly measure power, or the voltmeter part? Sure, what the heck. ;-) I've had Bird 43's, and calibrated line sections with matched elements for that matter, give erroneous reflected power readings depending upon what was going on with the transmission line. By erroneous, I mean it was usually a reading that was, for example, excessively high versus what we knew was going on, such as a straight piece of rigid line or coax terminated into a known good load. On rare occasion, we found we slipped a bullet or had a bad connector. More often, relocating the instrument somewhere else along the line resolved those bad readings. RF calorimeters can measure power directly. But unless they've one hidden in them somewhere, ThruLine meters can not. Just because the Commission might accept wattmeter readings, or Bird says so, doesn't make it so. As for the voltmeter part, check out page 6 of the Bird 43 manual (page 18 of the PDF), a copy of which you'll recall is here: http://www.repeater-builder.com/bird/pdf/bird-43-wattmeter-2004.pdf I respectfully submit what is shown is a schematic/diagram of a directional coupler attached to a voltmeter as an indicator. An induced RF voltage sample is rectified, filtered and applied through a dropping resistor to a shunt-connected ammeter. By definition, a voltmeter is the shunt-connected ammeter with series resistor part. But don't take my word for it. Take a peek at Chapter 25 in any recent ARRL Handbook (this works for my 2007 copy anyway). Is it less a voltmeter because the induced voltage tracks current on the line? Want to call it an ammeter or current meter then, after all that's what the actual meter movement is? I submit this particular voltmeter happens to be calibrated to read average power at 50 ohms impedance, and it does this quite well within its limitations. I now await your thrashing. Please be gentle. ;-) Like the manual says, the Bird 43 is fast, convenient and accurate. I agree it's fast and convenient. I'll agree it's accurate with the caveats expressed. It beats lugging a slotted line around, and it beats every other meter like it, IMHO, including my old Daiwa dual-metered POS wattmeter. ;-) Oh, BTW, the emperor has no clothes either. :-P 73, Russ WB8ZCC On 8/14/2010 10:11 PM, Kevin Custer wrote: Russ Hines wrote: Some related comments, if you don't mind.

Most modern duplexer designs (within the last 25 years or so) use compensating elements to make the duplexer or cavity temperature stable. Invar is a nickel-steel alloy that exhibits about 1/10 the thermal expansion as a common carbon steel counterpart. Invar is used to make the tuning rod - many times it's threaded. The rest of the duplexer or cavity is usually made of similar metals and generally thermal expansion occurs across these components equally, resulting in extremely low frequency drift over its rated operating temperature.

Re: [Repeater-Builder] Coax length, etc.
I see some folks are heading for the Advil. My apologies. Thanks, Gary, for admitting the 43 doesn't measure power directly. One myth down. Of course, it is a directional coupler, no argument. That makes it a reflectometer, it enables the instrument to isolate forward/reflected samples to some degree of reliability. What's the rest of the circuit? ;-) IMHO, what makes the 43 better than most (if not all) meters of its type, is the directional coupler is a true transmission line coupler, not a ferrite transformer, directly connected capacitor, etc. As far as rereading the manual, I have been. Bird's explanation requires the reader to suspend a standing wave viewpoint of transmission line theory, and buy into their traveling wave viewpoint. Uh, okay. But that kind of thing sends up red flags for me. I shouldn't have to suspend accepted transmission line theory to understand how their meter works. As it turns out, I don't. When line impedances get away from 50 ohms, accuracy falls and the meter behaves like you'd expect. It tracks whatever current is on the line at that (the meter's) point in the line without regard for impedance. Since it's just not calibrated for whatever that impedance might be, how can it be accurate? If the meter did as you suggest, then it would show what the voltage and current are at any point in the line, and therefore be able to tell you what the impedance is at that point, all with some level of accuracy. It simply can't do all that. Yes, Bird describes what happens when using 70 ohm lines with the meter under less-than-perfect conditions. IMHO, it's really messy. It can't tell the difference between a 1:1 VSWR and a 2:1 VSWR (both will calculate out to 1.4:1) on a 70 ohm line. That's not accuracy, that's nearly useless. BTW, my POS Daiwa can show me a 100% reflected condition, just like the Bird. And just like the Bird, it doesn't indicate if that's an open or a short. I believe Bird wants us to believe that their meter is faster and more convenient (it is) yet as accurate as a slotted line and calorimeter (sorry, nope). It's a calibrated voltmeter, not a network analyzer. For most everyday, mundane RF chores, it's just dandy as we don't really need high accuracy. And as long as line impedances stay reasonably close to 50 ohms, it turns out accuracy is pretty good, too. Certainly not bad for a portable instrument, and that's the point. If we remember what its limitations are, we should be good to go. That's why I own one and want more. Okay, I'm done picking nits.

But that kind of thing sends up red flags for me. I shouldn't have to suspend accepted transmission line theory to understand how their meter works. There are no standing waves that you can measure directly with the Bird meter. In order to truly measure standing waves you need to have a line length greater than a half wave length and measure where the nulls are along the line. Swr is calculated from forward and reflected power at one point on the line with a Bird type of meter. That's correct. As I said, the 43 isn't a slotted line. Regarding VSWR, all in-line meters make an attempt at this, some have fancy cross-needle indicators where VSWR is represented at the intersection of the needles. How else would you do determine VSWR with such a device? That was a rhetorical question. ;-) As it turns out, I don't. When line impedances get away from 50 ohms, accuracy falls and the meter behaves like you'd expect. It tracks whatever current is on the line at that (the meter's) point in the line without regard for impedance. Since it's just not calibrated for whatever that impedance might be, how can it be accurate? The Bird is set up so that the ratio of voltage and current that are detected work out to the power at 50 ohms. When the line is not 50 ohms that voltage/current ratio change that the meter detects. So you can no longer simply look at the scale on the meter and directly read power. For ANY reflected power reading you must subtract the reflected power shown from the forward power shown to find the true power delivered to the load. This holds true no matter what the impedance of the line is. Thanks, Gary, that's right. The meter is calibrated at 50 ohms impedance. When the line impedance isn't 50 ohms, you can't just look at the meter, the meter scale is no longer accurate, is it? Subtracting reflected from forward is a given, and never at issue here. Well, impedance does matter. At the characteristic impedance of the meter, line, load, etc., seems a waste of time to subtract nothing, you'll see right away there's no reflected power. ;-) If the meter did as you suggest, then it would show what the voltage and current are at any point in the line, and therefore be able to tell you what the impedance is at that point, all with some level of accuracy. It simply can't do all that. With the Bird meter you don't care what the impedance is because it measures voltage (by way of capacitive coupling) and current (by way of inductive coupling). Both create voltages that add together in the proper ratio to give the meter reading that represents power level for that combination of voltage and current. Gary, you seem to be contradicting yourself. A paragraph ago you said the ratio of voltage and current work out to the power at 50 ohms. Now we don't care what the impedance is? We either do or don't. As for me, I choose to care 'cuz that's the kind of guy I am. ;-) I understand the coupling, both are present, agreed. But if impedance didn't matter, then the meter would indicate power accurately regardless of line impedance. That's simply not so. The Bird manual even says it's not so. It's limited by its own line section. Yes, Bird describes what happens when using 70 ohm lines with the meter under less-than-perfect conditions. IMHO, it's really messy.

That's because there are as many rules as there are thumbs. ;-) I don't know about anyone else, but I can tell you about the highly scientific method I use. I start with a multiple of 1/2 electrical wavelength and trim as necessary. I'd stay away from an odd-multiple of 1/4 wavelength in this application... no good reason, just because (black magic and all that). Try cutting the transmitter-to-duplexer line using the receive frequency length, and vice versa. If that doesn't work out, you can swap them. I know, on a 2m amateur system, the length difference is about 1/4. In that case, make a cable 1-2 shorter and see what happens. An alternative is to use multiple short lengths of coax connected together to find a happy length, then replace with a single coax cut to that length. As I said, highly scientific. :-P 73, Russ WB8ZCC On 8/14/2010 2:59 PM, Ross Johnson wrote: So will someone post a simple rule of thumb...

Re: [Repeater-Builder] Coax length, etc.
Some related comments, if you don't mind. Temperature changes seem to be the biggest detuner of largely mechanical devices like cavity duplexers. We often send our repeaters off to live in less-than-ideal environments, then expect cavity input/output impedances to remain as we measured them in the shop? Don't think so. IMHO, we're making the same mistake I made in a post the other day, saying VSWR when what we really mean is reflected power as indicated on a meter. Jeff is correct, VSWR along a transmission line doesn't change if source, load and line impedances are stable, the ratio remains the same. What does change, and what is affected by line length, are actual impedances along the line under not-so-perfect-or-stable conditions; the actual impedances along the line change but the ratio does not. For example, 100+j0, 25+j0, 40+j30, and 40-j30, are different impedances yet all exhibit a VSWR of 2:1 in a 50-ohm impedance system. Voltage is proportional to impedance. We can't really have a voltage standing wave ratio greater than 1:1 without a voltage differential, and that really can't happen if impedances along the line remain the same. Our friends at Agilent have put together a Java applet demonstrating what happens along a transmission line. Maybe you're aware of it, it's really kind of cool. The applet allows you to change the load impedance of the model and see the changes, so have fun with it. http://education.tm.agilent.com/index.cgi?CONTENT_ID=6 Our in-line power meters, like our trusted Bird 43, do not directly measure power. They're really voltage meters calibrated in watts at a specific impedance. That's why they can be fooled into displaying an erroneous reflected power reading, perhaps lulling us into a sense of security that the VSWR on the line is acceptable when it may not be. With most transmitters I'm familiar with, a high VSWR condition is detected from a reflected RF sample from a directional coupler at the transmitter's output, so it's not a real VSWR measurement per se, it's a voltage measurement. Worse, these couplers tend not to be very selective, so out-of-channel and even out-of-band energy can cause high VSWR trips even when our measurements indicate all is well on our frequency of interest. Great discussion, keep it going. If I repeated what was already mentioned, my apologies. 73, Russ WB8ZCC On 8/14/2010 12:53 PM, Kevin Custer wrote: Jeff DePolo wrote: Because the impedance is not matched between the transmitter and duplexer, the 'apparent' loss of the duplexer is greater than the manufacturers stated loss of the duplexer. Changing the cable length is not changing the loss of the duplexer, it's changing the power that is accepted at the transmitter port of the duplexer by matching the output impedance of the transmitter to the input impedance of the transmitter port of the duplexer. But if the duplexer is tuned to 50 ohms, and the cable is 50 ohms, varying the cable length isn't going to change the Z seen by the transmitter. Or are you suggesting the duplexer is purposely de-tuned from 50 ohms? Purposely, accidentally, by lack of good design - people not having the right equipment to tune it correctly - whatever. And also that by varying the cable length between the transmitter and the duplexer that you can vary the reflected power on that same line? Yes. With all due respect, that's not possible, regardless of what the Z is of the duplexer. The only time it could have an effect on the reflected power would be if the transmitter/PA were spurious, and the amplitude/frequency of the spurs changed with varying load Z, and I think we can both agree that if that's the case, we have bigger fish to fry. And this is where I believe the duplexer manufacturers are covering their butt. They don't want the problem with complex reactance presented by the duplexer to be their problem. Not that I don't agree, because it's usually the transmitter that is really at fault. Joe Ham buys a new duplexer and hooks it up to his 110 Watt MASTR II repeater and gets 50 watts out the antenna port. He does his homework and realizes that he should only be loosing 29% with the 1.5 dB of insertion loss stated in the paperwork - but he's loosing over 50%. The duplexer manufacturer supposedly engineered and tuned it for a 50 Ohm system. He knows that the cable he connected to the transmitter is good, because when he disconnects the end going to the transmitter port of the duplexer and connects it to his Bird 43 terminated with a good load - it reads 110 watts. Now, is the transmitter becoming spurious and the cable length being changed in length satisfies the match between the duplexer and transmitter - I don't know... All I can tell you is I have followed the suggestions written in the WACOM manual and it has worked. I had one instance of a ham radio club

Jeff was correct to question. I was vague. What I should have said was indicated reflected power, not VSWR. But good luck trying to determine an accurate VSWR based on erroneous reflected readings.

Re: [Repeater-Builder] Coax length, etc.
Thanks, guys, a good topic and one that always seems to come up. And it sparks more questions and comments, of course. The cable length issue is a brother to if you don't like your VSWR, change the point along the transmission line where you're measuring it. By changing the length of the line, we're creating a transmission line transformer (a good thing) but we're limited by its length (not so good). It seems to me the mentioned circulator/isolator at the output of the xmtr is a better fix, as reflections coming back from the duplexer is absorbed by the circulator's load, the xmtr is generally happy, and we're no longer limited where we can put things in a rack or elsewhere. For amateurs, coming up with usable VHF circulators seems to be difficult and usually expensive, and coax always seems to be cheaper. Has anyone had luck finding a source for reasonbly priced VHF circulators, or success in rolling their own? Also, I noted in the pamphlet Kevin referenced that the unused duplexer port was left open (Figs. 1 2). I guess if the isolation is already greater than the load's return loss, it doesn't matter, at least at the reject frequency. But it seems to me one could possibly create problems for oneself by not terminating the unused open port. Just a thought. Maybe I work better knowing there's a load there. ;-) Your comments, please. 73, Russ WB8ZCC On 8/5/2010 10:19 AM, Doug Hutchison wrote: Hi Kevin and all who responded to my question.

Hi guys.. This is a good thread.. I've been wondering about the decibel UHF harness for a long time. SO.. If I'm reading Chuck right, the DB UHF elements are 100 ohms.. Correct me if I'm wrong, but doesn't this mean I could pull 2 of the elements off a DB408 and make a DB404 by simply connecting the elements by equal lengths of some good 50 ohm coax to a T, and attach a 50 ohm feedline to the T??

Hello Henry. I believe the COS on the GM300 is active LO. Open collector.. Try using something like a 10K pull up resistor tied back to 12v.

RE: [Repeater-Builder] Help with Motorola Radius M120 - Intermittent Recieve
Hey Scott. Thanks for writing back. You did some work for me not too long ago. I sent up a spectra-tac receiver that you retuned for me while Kevin was busy somewhere. We swapped the vibrasponder tone element too. I needed 131.8, and you took what was in it and put that one back in.. Remember? Anyhoo... I got this unit about a year ago, and it looked brand new.. Not a scratch on it. Still had that new smell too. I employed it as a IRLP link radio. It's a 10w unit. I'd often try to operate the IRLP node and it would not respond. Turned out to be this unit's receiver. I opened it up last nite. Looked totally virgin inside. I cleaned the connectors where the boards(top and bottom) attach to the chassis. I had to take the lid off what I'm assuming is the VCO compartment to get at a couple of screws to lift the board. It's the shiny lid that presses down over a couple of sections inside the radio, correct? I'll open it up again this evening and take a measurement at the test point you indicated. I'll assume I don't need a signal present to make this measurement. Might be good if you could give me a pointer to location of the RX VCO coil too, so I can tweak if it's out of spec.. Is it labeled? What voltage would be considered acceptable? 7 +- 2v or so??? It really doesn't seem temperature related. The unit operates in a climate controlled room. I may send it up to you for a look if I can't make any headway, if you work on these... 73s, and thanks again for writing back.

An LO that was off would rear its head as sounding off frequency or poor sensitivity. I have had some problems with the LO crystals drifting as of late, but I don't think that is your problem from the description you provided. At any rate, the second LO crystal frequency is 44.645 NOT 45.645. The IF frequency is 45.10, so 45.100 - 44.645 = 455KHz. It sounds to me like you might have a broken/cracked solder joint somewhere inside the radio or that the Rx VCO is going out of lock. Does it seem to be temperature related? If so, that would lead more toward the VCO. You can open the radio and VCO compartment and see what the voltage is on the test point marked SL. It should be around 7v or so. If not, you can adjust the Rx VCO coil to get it more in-line where it needs to be.

[Repeater-Builder] Re: Solar Power
Hey Tim, The Santa Fe Amateur Radio Club has opperated a solar powered repeater site for over 2 decades. Here is the link to their repeater site: http://www.w5sf.com/repeaters.html Its the Elk Mountain site. The site was initially a FS repeater site and using automotive batteries and 2 solar collectors. In the picture, is the new building and tower, the old building was a Montgomery Wards type metal shed and a rohn 35 tower. The tower came down during one winter and was replaced with a self supporting tower, and a pre-fab building. Ofcourse its over 11k ASL. At times we have had snow covering the panels and the repeater was dead until the sun recharged the batteries. Thankfully we have a wind gen up there now so the batteries have a constant supply of energy. The current site holds; APRS node, FS repeaterX2, FD repeater, VHF Ham RepeaterX2, and a UHF linking repeater. The power side of it; 1500W Wind turbine, ~6 Solar collectors(cant remember the total, i think six), charging system, and the battery bank consists of 12-2V 1480AH, running two pairs of six batteries(12V). Each battery weights: 250lbs. Recommendation for any solar site is: armor plate your power system. 1/2 plate is what we use around our batteries.

Re: [Repeater-Builder] Best Controllers
Hi,all Pac Res is still there and makes several, some ham-bound. We have 3 of the RI-300 series on CARA and they work acceptable. However, programming is very difficult and there is no real-time clock so whenever there is a power bump, the controller sends a time not set message with every id. In the programming, the code doesn't wrap around but merely steps onto the next line replacing whatever was there. A trap which is not difficult to avoid if you know it. Either put several calls to another address or plan ahead and leave some blank lines between each command set. Learned the hard way. My two cents worth Thanks Russ AE6UX --- Jim B.

Re: [Repeater-Builder] Re: Side mounted DB-224 for omni coverage?
I have a few with all the dipoles pointed into the tower and one wavelength off the tower at the transmit frequency and it works just fine and is fairly omni. some DB-224's on 220 and some on two meters. 73 Russ, W3CH There will ALWAYS be some null in the direction of the tower at any practical distance away from it at 2M. I think the idea of facing the dipoles toward the tower is a way of putting maximum signal toward a known weaker area. The pattern will never be omni with a side mount, but we can try...

Re: [Repeater-Builder] Side mounted DB-224 for omni coverage?
Here is how my DB-224 was done. You mount it one wave length off the tower at the transmit frequency. Point all four dipoles at the tower.

Hello Group, Have a dual antenna system for a 2M repeater. Decibel DB-222 top mounted, clears the tower and is oriented for omni-directional coverage. TX antenna is directly below and is side mounted on the southwest side of the tower. The antenna is a Celwave PD-340-3 with dipoles oriented around the mast (omni). It is mounted on the corner (not the face) of Rohn 25-G and is a factory mount and top sway brace from Decibel Products and they recommend this for side mounting DB- 224's. The mount lets the antenna extend around 22 inches from the leg of the tower. I am noticing VERY significant deficiencies in TX coverage back through the tower, even what I would estimate 8 to 10 dB. In other directions, it seems as if the coverage is as good as can be predicted. I have heard someone mention that taking all four dipoles on the same side of the mast and directing the elements straight into the tower would create more of an omni pattern. I can't remember if this was for UHF or VHF. I would like to eliminate any deep nulls, no more than 3 dB down in any direction if possible. Will turning all elements towards the tower help my situation? Yahoo!

Re: [Repeater-Builder] UHF ham band offset dipole array availability
DB and the Ham cut. There new policy is you have to buy 50 of each antenna to get it in the Ham band. you can still get the DB-404,408 and 420 in the Ham band as long as the dealer you are dealing with is welling to buy 50 of each and sit on them till the next Ham buys one..

The typical 5/8 wave mobile antennas have 3 dB gain, some of the ham-grade antennas claim 7-8 (and even 10 dB gain). I occasionally get asked, why do you use one of those expensive, low-gain Sinclair, Celwave, etc. antennas instead of Hustlers, Diamonds, etc that have so much more gain? Even the big Scala OG-4 2-Meter antennas are 4 dB gain, if I remember correctly.

Re: [Repeater-Builder] 220 Mhz. repeater
Do your really build repeaters? Converting a GE or Motorola is not building. Is it? I have done my share of Master twos and Micores but I did not build them. Just moved them into the Ham bands and maybe duplexed them but I did not build them. Motorola or GE built them. I did move a Johnson or two as well. So before you get up on that soap box that you are building a repeater think about it. You are not building a repeater you are buying an old GE or Motorola that some one else built and adding to it. Or moving it into the Ham bands. Just my two cents. Converting is not building! Very best and a good Easter week end to all. I will be away so I will not even get to see the flames from folks saying they build Motorola or GE radio's you are only kidding each outer. 73 Russ, W3CH, - Original Message - From: Dexter McIntyre W4DEX [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Thursday, March 24, 2005 9:04 PM Subject: Re: [Repeater-Builder] 220 Mhz. repeater Perhaps the repeater buyers would like to start a Repeater-Buyers group and leave the technical challenges to real repeater builders.

Re: [Repeater-Builder] Re: portable/mobile GMRS repeater antenna
Hello All, I can say that I feed my antenna on my Port-a-peater from the duplexers to the antenna with Beldon mil spec. RG-214/U it is silver and I use type N connectors on it, the duplexer is TX/RX and of Crosse the repeater is a Kenwood TKR 850 (non ver. two) it can be installed in about 10 minutes and will run all day. I forgot to add one thing I have a solar battery charger that just lays on the hood of my SUV to keep the battery up. The fold over mount is from Tar Heal antennas in NC and the 20' piece of pipe came from a scrap yard. The whole key is the fold over mount. The DB-404 I had from a early GMRS repeater site before I up graded to a DB-420. The above is my whole system and it works very well.

Laryn K8TVZ I would mostly agree with this statement, but the person asking about this is looking for answers that will work in a specific application. I have used RG-8X and even RG-58 with excellent results in duplex systems, especially when the power is relatively low. I suppose the thing to do would be to use a DB-420 and 7/8 inch heliax, but this would be impractical for most mobile/portable repeater setups. There are lots of possiblities of things that could work for this application, I am only speculating on one thing that I personally know will work, not saying it is the best, or most desireable, but something that could be looked at for this particular scenario. Quarter inch or half inch superflex would work too, just don't know how much money a person has to invest in a particular project. People that are contemplating a project need to be given some direction by people who have done similiar things, that way everyone doesn't have to re-invent the wheel. The more ideas people are given, the better they are able to asess which will fit their needs best.

Re: [Repeater-Builder] Re: which kind of cable coax should I use?
I would not buy used Hard-Line type of coax. I know many do but I will not. If you have a TDR and can sweep it then you mite be OK and know that what you are buying is good. Used if they do not seal up the ends some times gets water in it and you just got took. But you can buy new Andrews, RFS or Comscope at a good price from most suppliers. At 50' 1/2 will work just fine. If the Hard Line was a take down there mite be a reason that it was removed from service. Yes you can get some deals on Hard Line some good and some bad. If you can't sweep it beware. Hard line is a funny Animal and can look brand new and be bad. I would still use 7/8's my self. The same place you buy your hard line will have the connectors and most of the time will install them for you.

Re: [Repeater-Builder] which kind of cable coax should I use?
I would use 7/8's hard line type coax. You can use 1/2 as well. I would not use Times microwave LMR-400 or Belden 9913 type of coax. You can find a list of suppliers on the Repeater-Builders web page to price or buy the above hard-line type of repeater feed line from.

They moved it above the 450 antenna and all was well again. You may wany to pay attention to exactly which channels they want to use, as I believe some of them are actually IN the ham band. Joe M.

Re: [Repeater-Builder] A big THANK YOU!
Hey Dex and the group, Well 3 DB will double as we all know every 3 DB doubles your signal. Yes it did work and no the DB-224 was not broke. It worked just fine and we will use it at one of our newly planned sites. But just like every one said the DB-228 is a monster and will work real well. It does do that. The WX this morning is fog and rain and the repeater is still useable here in Glassboro NJ and it is all the way down in Ocean City NJ. I am very happy and feel it was money well spent. 73 Russ, W3CH - Original Message - From: Dexter McIntyre W4DEX [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Thursday, February 10, 2005 6:42 AM Subject: Re: [Repeater-Builder] A big THANK YOU! russ wrote: I would like to thank every one who told me about the DB-228!

Re: [Repeater-Builder] Hustler G6-440
Good morning Jeff and the group, I have not had the best of luck with the Hustler G-6 why do younot look into something like the DB-404 if you need a lower end antenna. It will hold up nice. Or a mid priced DB-408 more gain just a bit higher in price. Or for some real gain the DB-420 all will do better then the G-6 and all will last a whole lot longer. Plus real gain and much better built. I would research the commercial antennas before spending money for a Ham grade repeater antenna. This has been my findings over the years. Before any one un knowingly says they do not make them for 440 WRONG! A suppler has to buy them 50 at a time then stock them till we buy them (we being us Hams.). So yes some suppliers do stock and sell the DB-404, 408 and yes even the 420. Good luck!
