Hello Guys and Gals, Recently Tree did some work for me and one of the things was to put up the Comtek 80 meter 4-Square switching unit and a couple of pulley setups for my raising of the 80 meter sl

Terry, I assume you only installed ONE sloper and made your measurements ? With all 4 installed there is way to much mutual coupling to get a meaningful reading. If your readings were from only ONE a

Yes, install ONE sloper. . .measure and cut to resonance. Duplicate that measurement for the other three. 73. . .Dave, W0FLS Terry, I assume you only installed ONE sloper and made your measurements ?

Essential point that might be missed: each one of the elements, one at a time, must be tuned independently with the other three elements down. This is the initial tuning. If when everything hooked up

Interesting. This is not how I tuned my 40m 4-square, albeit with tubular elements not slopers. Anyway, my understanding is that you disconnect all four elements from the control box and measure at t

You dont have to lower them but you need to short them to ground to make them electrically invisible _________________ Topband Reflector Archives - http://www.contesting.com/_topband
