Very interesting, reading as always, This brings me to another question, how do I need to handle grounds in a switch box with 3 antennas ?

I've done this for 31 years from 3 different locations with no problems. From a 2011 post on this subject: ZL3IX wrote: >* As long as your relays have decent isolation, even for high impedances,* it may even be better to switch the Bev wires themselves. That way you don't share the ground at the feed end, and avoid any common impedance coupling. I agree. I've done this since installing my first set of 7 Beverages in 1985 arranged like wheel spokes and have never noticed crosstalk problems. I even sometimes switched two in parallel to listen in two directions simultaneously in contests (NE and W when I was in Colorado). Now I prefer diversity (Beverages on one RX and an RX 4SQ on the other RX) for contests. 73, Bill W4ZV _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
