Hello to the group. I am considering making a homebrew HyGain HyTower. My first questions is this: The stinger at the top is not electrically connected to the top of the tower? It is insulated and th

I live in an area (SW FL ) which has an average of 90 lightning days per year. We really get hit hard with lightning. Is there any way to avoid a direct hit on an antenna by painting the antenna or c
I have an A3S Tribander on my tower and I want to add the A3WS 12/17 meter yagi above it. I have 7 ft of available mast above the A3S. Is there any problem with mounting the 12/17 m yagi at 7 ft abov
I am planning to mount the Cushcraft A3-WS above the Cushcraft A3S. Most people have replied 7 to 8 ft separation and Cushcraft says 7 ft is OK, in fact even 3 or 4 ft is OK since both antennas are N
I am looking to understand how the HyTower can be advertised as a 1/4 wave antenna on 80 meters. The standard 1/4 wave length at 3.6 MHz is approximately 65 feet, yet this antenna is 53 feet tall on
I have the Cushcraft MA160V vertical for 160 meters. It is tuned for the low end of the band. Is it possible to add some tuning at teh base that can be switched in/out to get higher in the band as ne
Allan Is this choke for bleeding off static? I the answer is yes, just use a 100K or larger resistor rated for a few watts. Personaly, I have a choke that HyGain sells as a spare/replacement for the
Hi Dave, These are pretty much what HyGain puts on their AV-620 and AV-640 antennas. I had a spare and put one on my 160 meter vertical. In addition, I also have the I.C.E. Lightning suppressors on m
You may need a lot more than 12 turns on that choke ( Ugly Balun ) . I tried 15 turns and I still got RF in the shack. I doubt that this is his problem. I went through hoops making my 6BTV work. Fina
That is a 6 BTV if it has 80 meters, right? I have a 6 BTV and I seem to recall that I had to adjust the length of aluminum tubiing above the 30 m trap. That meant cutting it. Before you do that, I s
I find that my MFJ analyzer is in complete agreement with using my radio and it's built in SWR meter. All of my antennas have random lengths of coax. I have never had to adjust coax lengths. However,
As I said earlier, I struggled with this antenna myself. I only bought it for use on 80 meters. I also use the HyGain AV-640 which works on 40 through 6 meters. Fabulous antenna. Worked the world wit
One thing that I found with mine when I was initially installing it: After I made an adjustment of the tubing length, when I rsaised it back vertically, the tubing sections would slide from the weigh
David Look really hard at the HyGain AV-640. I have been using one for 5 years. It is a winner !!! 3/8 wave vertical which gives low angle radiation. No radials. You can mount it 7 ft above ground fo

I have been using an AV-640 for 5 years. Once a year, I lower it and clean all mechanical connections end to end. Small wire brush. All aluminum connections to screws etc. On the 17 m stub, if it vib
Having been a calibration Engineer in my early days, I concur with Jim. In addition, each coax connector inline introduces losses. They all add up. Definitely worse in VHF/UHF. Some folks say you can
A really serious DXer is concerned about these losses. Someone who casually operates may not care too much. The point is that all losses add up. I CAN hear the difference. For example. +/- 3 db is ei
