Yea I know I'm going way overkill and I was doing all the calculations by hand of total loss and at a 7:1 SWR (which is entirely possible on this 43 ft vertical) the loss at 30Mhz can get kinda ugly... I've not modeled it fully but on all bands but on 20 meters its 7:1 and on 40 meters its 3:1...
I think I'm just going to call it a day and use the LMR400... But its fun to overthink this stuff... Article looks nice I can see I'm going to be up for a few more minutes! ;) ~Brett (N7MG) On Tue, 2010-06-22 at 23:34 -0700, Jim Brown wrote: > Check out > > http://audiosystemsgroup.com/Coax-Stubs.pdf > > 100 ft of almost any decent RG8-size or RG11-size coax is just fine for a > Field Day antenna on the HF bands.
