[Repeater-Builder] lightning arrestors
Hi all, I had a question that I believe some of you can answer! I have a repeater with an antenna only about 20 feet off the ground here in Florida and am now looking for a budget lightning arrester. I have seen so many different ads I figured I would go to the horses mouth and ask you all if you have to do it on a budget what did you use? Did you mount the arrestor outside with an appropriate ground or inside? By the way the antenna is low because of the community regs. and it does cover the community for GMRS emergency work at that height. Thanks Steve N4YZA Yahoo!

RE: [Repeater-Builder] lightning arrestors
Steve, I use Polyphaser arresters for my repeater system... I prefer not to think of any lightning protection system or component as budget - all you need is to take one lightning strike, and budget goes right out the window!! I planned for expenses related to lightning protection when I started my project, and budgeted accordingly. My arrestors are at the point where the cabling comes into the building... single point ground. I believe you'll find almost everyone here does the same. Save yourself the heartache and get good lightning protection at the get-go. Even an antenna 20 ft up can get bit! My 2¢ worth, anyway...

The going price for Polyphasers are about $65.00 wholesale. They are available with UHF and N Type Connectors. When I use my spare, I go to E-Bay and start watching. I buy them for about $25.00 IN THE BOX. Make sure you check the frequencies that you bid on. They come in different frequency ranges and power.

Re: [Repeater-Builder] lightning arrestors
I prefer Alpha Delta. They have one model that covers all frequencies and is rated for 200 watts. They normally have UHF connectors; you have to pay $5 more for N connectors. They're about $50 new. I get mine from Universal Radio, HRO, or AES. The commercial site where my 900 MHz repeater is, has a bunch of PolyPhasers, so I bought one too. For that band, it's only good for 50 watts, and I don't think they had one rated for more power. So I had to replace it with an Alpha Delta; I should have just bought that the first time.

Re: [Repeater-Builder] lightning arrestors
There are some decent units made by other companies than PolyPhaser. I.C.E. is one that comes to mind. However, your real expense isn't with the feedline protection. Keep in mind that you will need to have powerline protection and a single-point ground system. The grounding grid will likely cost you more than the lightning arrestors since you are in Florida - land of tough to get good ground. You'll need lots of ground rods and lots of large copper ground wire to construct a ground grid. This all needs to be bonded to phone and power grounds too. There's way more to it than simply putting a lightning arrestor on your coax. PolyPhaser wrote a book on it. Start looking for this information. Without doing it right, forget the lightning arrestor on the coax and buy insurance instead. Chuck WB2EDV Stephen Rice wrote: Hi all, I had a question that I believe some of you can answer!

Thanks Steve N4YZA Steve, You asked the question so be prepared for the answers. Budget lightning arrester is an oxymoron. Personally, I prefer to use the Polyphaser line of suppressors. They have a broad spectrum of equipment for different applications. As someone mentioned, ebay can be a reasonable source for these if you can get new equipment and check Polyphaser's on-line spec sheets for appropriateness. Polyphaser has a track record of excellence. Everyone else seems to be an Also-Ran or Wanna-Be and is a gamble. Polyphaser has some very good information on their website that should be required reading for anyone that sticks things in the air. As important as grounding for your equipment is bonding. When, not if, lightning strikes all equipment needs to rise and fall at the same potential. Copper strap is your friend. Copper braid is a waste of time. Lots of info on web about doing it right. Usually, the Polyphaser is mounted at or near the entry point to the building and bonded to the single point ground that should be near with a #6 or larger copper wire or better, a flat copper strap. A case can be made for having another Polyphaser at the equipment as well. 73, Al, K9SI Yahoo!

RE: [Repeater-Builder] lightning arrestors
The commercial site where my 900 MHz repeater is, has a bunch of PolyPhasers, so I bought one too. For that band, it's only good for 50 watts, and I don't think they had one rated for more power. So I had to replace it with an Alpha Delta; I should have just bought that the first time. Bob M. == The high-power (500+ watt) Polyphasers are usually advertised as being combiner protectors. They are made for various bands. In fact, if anyone has a need, I have a surplus of the UHF ones rated for 500 watts. --- Jeff Yahoo!

RE: [Repeater-Builder] lightning arrestors
Steve, This is a topic that has many proponents of certain brands or grounding methods. I liken it to the way some people (usually guys) talk about motor oil. You know the type: Well, I never use anything but Castrol GTX in MY car! The guys who say this have no special laboratory equipment or technical background to justify their position, but they crow about its benefits and offer the fact that their engines haven't blown up in 20,000 miles as proof of its superiority. Okay, I know a little about lightning protection, having worked as an EMC engineer on the Space Shuttle program. NASA did a huge amount of research on lightning at Kennedy Space Center in Florida, sending up small rockets that trailed a thin copper wire that actually triggered a lightning strike. There are hundreds of test reports in the NASA archives that document how lightning affects electronic equipment on the ground as well as manned space vehicles. I read most of those reports, and had the honor of meeting Dr. Philip Krider, one of the world's experts on lightning. I know that Polyphaser is a popular name in lightning arrestors but I wondered why I never saw that brand being used at a cellular telephone site. The brand I did see at most cellular and commercial sites was Huber + Suhner. So, I bought one of each brand, both of them specified as a bulkhead mount for 150 MHz and 100 watts. The Polyphaser unit was about $70 and the Huber + Suhner unit was about $125 with the proper gas capsule. The physical differences were considerable: The H+S unit was waterproof while the P unit was not; the H+S unit was completely machined out of stainless steel while the P unit was made of two diecast aluminum pieces; and the H+S unit had an easily replaceable gas capsule while the P unit had a soldered-in-place capsule. The real difference was in RF performance: the H+S unit had no impedance bump when tested on a network analyzer while the P unit had a prominent bump. And I can see why- the P unit has an asymmetrical jumper inside the case. Since cellular telephone systems operate generally in either the 880 MHz band or the 1900 MHz band, any impedance discontinuity can have significant and detrimental effects. But, let's get back to the lightning protection issue. Most high-quality antennas used with repeaters are DC grounded, so it is likely that most of a lightning stroke's current can go straight down to Mother Earth, instead of taking a side trip into the repeater equipment. Aluminum dipole antennas are favored for mountaintop sites simply because the mast itself- which is a good conductor- projects above the active elements and acts like an air terminal. However, even if the bulk of the stroke current goes into the ground system, there will be a high voltage spike going through the feedline. Ideally, the lightning arrestor should trigger at a voltage just above the voltage caused by the transmitter. A 100 watt signal in a 50 ohm circuit will have a peak amplitude of about 100 volts, so we want the gas tube to conduct when the voltage reaches 125 volts or so. If the gas capsule doesn't trigger until 500 volts is reached, a lot of damage can occur. What is nice about the Huber + Suhner arrestors is that the gas capsule can be selected to closely match the power level of the transmitter, thus affording maximum protection to the equipment. Go here for more info about Huber + Suhner products: http://www.hubersuhner.com/products/hs-p-rf.htm One thing to consider is that, regardless of the brand you choose, when the gas capsule triggers, it places a dead short across the feedline. If your transmitter is keyed when this short occurs, the power will be reflected back to the PA and may cause damage. It is always a good idea to have an isolator at the PA output to handle this momentary power reversal. Finally, I completely agree with several other posters who mentioned that a lightning arrestor on the feedline is only a small part of a properly-engineered lightning protection system. The tower itself should have a very robust grounding system, which should be solidly bonded to the building electrical and communication system grounds. Both the electrical supply and the communication (telephone) circuits should have surge protection. One of the most authoritative references for the best practices in this regard is the Motorola R56 Manual, also known as Standards and Guidelines for Communication Sites. The printed version, which comes in a nice binder, is 6881089E50 for about $85. The CD-ROM version is 9880384V83 for about $64. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Stephen Rice Sent: Thursday, March 02, 2006 6:51 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] lightning arrestors Hi all, I had a question that I believe some of you can answer!

YES! was this reply, $33.55 plus shipping. Now thats better. The aluminum is in gud shape but the lighning hit destroyed the the coil. The antenna still had low SWR and no desense but the performance fell off. The noticable drop in performance may me examine the site and notice the top half of the antenna was missing. Found the top half and hopefully will be able to put it all back together with new coil and have a spare antenna on ready.

After they got the original antenna down, they could finally see what had happened. Thor had come for a visit. Melt-through, two holes near the top of the mounting mast, and when they tried to pull the two sections apart, they were arc welded together. Two strong guys couldn't pull the sections apart. It'll be interesting when they get around to doing the internal autopsy and looking at the harness to see what else is cooked. If I can, I'll get some photos.
