Hi, Bill, Even though the beams on your monster tower have all elements insulated from the boom, the driven elements will still add to the top loading because their feedlines running down the tower t

I have compared the Icom IC-756pro2 with my FT-1000MP and Elecraft K2 in an A/B test on digging real on-air weak CW signals out of the noise on 10 meters and 160 meters. The 756pro2 performed best on
