I'm making good progress to get my KLM and Cushcraft antennas mounted on the roof.I think I'll be able to wrap it all up this weekend.
I do have a question about the polarity switch on the Cushcraft 30 element 440 antenna. The switch has one lead that seems to be intended go to +12vDC and the negative lead goes to the boom of the antenna. Do I need connect -12vDC to the coax on my feed line in order to complete this circuit? Seems easier to just disconnect the wire from the boom and run it to a dedicated -12vDC lead. My switch on my KLM is fed with dedicated leads for + and - and it seems that would be the easiest way to deal with the Cushcraft. Am I missing something obvious here? I have wires to spare and can so it's not a big savings to me to run the -12vDC on the coax if that is the reason why this was designed this way. Pointers and suggestions welcome. 73, David _______________________________________________ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
