It seems like it could be done. You will need the right-sized aluminum pieces for the lower section and something for the upper, which I would think you could also do with wire. To calculate the dist
Even better, do a search for LMR coaxial cable on the wallmart web site. They offer LMR-400 and other types thru 3rd parties. I have not compared their prices though, but knowing wallmart, yhey shoul
Elevated radials. I know all the science is good (I am an engineer after all) but what I found easiest to do when I constructed my 160m inverted-L was to attach a 500' spool of wire to the base and r

The rule of thumb is ½ the wavelength of the highest freq. band so about 9.5 would keep the HF antenna out of the capture area of the 6m beam but of course the opposite would not be true. The 6m beam
I own a TX-472 tower. The top section of which is the standard triangle that is 11-7/16 per side. While a Hygain Ham IV will fit inside with sufficient clearance when the tower is lowered and all the

Youre lucky to be able to string so many radials on the ground. I happen to use a single, tuned, raised counterpoise wire and my inverted-L works just fine. I wonder if anyone has compared the differ
I just purchased a used/never used Alpha Spid Rotator and am wondering if anyone has any lessons learned that they would like to share. I am upgrading from a T2X and am looking forward to the increas
I also have a Microham StationMaster (as well as some of their other products) and think its a great addition to shack automation. Like you I use it to perform several tasks, including antenna switch
Has anyone found a good waterproof connector / kit to replace the terminal strip in Alfa-Spid RAK rotors? I really dont like having to waterproof a direct connection to a terminal strip, they never s
I have a 1980s vintage Cushcraft A4 and just replaced it with a 3 element SteppIR. I had the 40m add-on as well and never had a problem with it. 15 meters was its best band. Only once did I take apar
