[Repeater-Builder] Re: antenna plan
I think you would be much better off getting a folded dipole antenna like a DB224 for VHF or a DB411 for UHF. You can set the dipoles to favor the town by putting 3 facing the town with one left facing the opposite direction so the back door isn't too badly affected.

Thanks Joe and Jeff for the instructions. From the Celwave sheet I guess the model number of my circulator may be CC460-AA, the model number is stamped so close to the sticker border that the second A would be off the border... In the meantime I also found a helpful document, also uploaded it to the files section, it's called 'EMR-Single-Isolator-Tuning-Instructions.pdf'.

Re: [Repeater-Builder] antenna plan
Then I'd take a DB-224 antenna and point the elements toward your desired areas. If you split and mount another antenna elsewhere, you are going to create a highly unpredictable pattern with two different radiation centers, creating multipath possibilities. At least that's my take.

Your omni + yagi configuration will work. It has been used in the land mobile field for many years, but not very often. You get a keyhole shaped pattern.

Re: Low Band Antenna for both 6 10 meters. Scott Zimmerman n3...@... wrote: Skipp, How did you work the antenna scheme for this radio? Hi Scott, There are a number of available options. First, I've seen but do not own one of the Comet/Diamond multi-band antennas that does cover both bands plus. I saw one on the back of a guys car at a local flea market and he said it covers multi-bands including both 10 and 6 meters. Don't remember if it was a Comet of Diamond but it was one of those two brands. Another method is to diplex two antennas for each band if you only want to operate within the range of the antennas. There is another trick to cut the antenna long and use a band-width expansion box as previously sold by Antenna Specialists. Probably discontinued by this time... A method to obtain bandwidth at the cost of performance is to use a shortened vertical with a fairly lossy matching network. It's a big time trade and well out of the scope of an easy explanation here on the group. And in a no good deed goes unpunished application I have something similar to an improved Maxcon Antenna Matching unit talking to a number of vertical whips I can swap in and out. An acceptable very wide bandwidth SWR talking to a very lossy antenna matching system antenna is better than no antenna a'tall. Did you use the Motorola docs, or some other method? The Catholic Church says only the rhythm method is allowed. http://en.wikipedia.org/wiki/Calendar-based_contraceptive_methods In my app, I am going to be using a Syntor X on 6 and 10.

I once worked in the aftermarket autosound industry, where springy, one-sided blind nuts were used to mount speakers in places you couldn't see.

[Repeater-Builder] Adding capacitors to lower electric bill
A while back, maybe a year or two ago, there was a discussion on here where a list member had success adding a capacitor to his electric service which reduced his bill. It was debated for a while. Anyway, I am wondering if the utility company ever came and replaced the spinning disk meters with electronic versions, and if so, what the outcome was. Could the original poster respond either here or privately? I just today had a similar discussion with another ham who tried essentially the same thing with no success - only his was a commercial model, so it cost him considerably more. Chuck WB2EDV

That's my take, but someone on here insisted otherwise based on testing he had done.

Re: [Repeater-Builder] Intermod Calculation
2A-B solving for once for A and once for B. Or, to make it more clear (maybe), the sum of your receiver and half the difference between the two (IOW, the frequency directly half way between two two others), and the sum of the full difference plus the paging transmitter frequency. Putting it another way which might be easier to understand: The frequencies half way from your RX to the paging TX, and the frequency twice as far from the two (in the direction of the transmitter) Either way, it's all 2A-B: 2(151.140) - 157.740 = 144.540 2(157.740) - 170.940 = 144.540 Joe M.

It's been a while since we needed these, but I used to make them all the time for low band fire (33.70 and 46.38). As I recall, the stub is a short to the opposite frequency - making the antenna appear to not be there. Hence, all the power goes to the 'on frequency antenna'. Congrats on the third harmonic, BTW.

RE: [Repeater-Builder] Adding capacitors to lower electric bill
True power (W or KW) is increased by poor PF and high apparent power (VA or KVA). The resulting increase in current demand raises the true power but the extra current is usually lost as heat instead of performing work. The bigger problem (bigger than an inflated utility bill) is the potential for fire from drawing too much current through a branch circuit that can't handle the highly reactive load that's been connected to it. Also beware of cyclical reactive loads on panels that also feed electronics. I recently troubleshot a commercial 3 phase panelboard feeding both UPS's and across-the-line HVAC gear (a bad combination). The UPS's were failing and the owner didn't know why. A quick power quality analysis showed it was due to excessive UPS transfers caused by the HVAC cycling during the daytime and causing the UPS's to see voltage dips. Average PF was .67 when we started, .91 when we moved the HVAC away from the panel and did some load balancing.

[Repeater-Builder] Re: Adding capacitors to lower electric bill
When in comes to matters of science, there will always be some who step forward with anecdotal 'evidence' that they have experienced something that contradicts accepted scientific knowledge. Using caps to reduce your power bill is one of those myths. Your power meter is a true watt meter, and is very carefully designed and tested to measure, react to and record only true watts, and not react to reactive power. (pun!!) Yes, installing corrective capacitors can reduce your power bill, but not because it changes your meter reading; it doesn't. For industrial users, a poor PF results in penalty charges from the utility, and improving the PF by adding capacitive VAs ( or KVAs) can reduce the penalties, thereby reducing your bill. This is not really a repeater topic, but power bills are a real part of repeater use, so it is useful to understand the real 'science'.
