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 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

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
