Interesting stuff from you all on success of using a quarter wave vertical for 80. Yes it does also play on topband. I am using remote relays at the base of the vertical, I switch it from 80 meters t

Mike, No need for traps and horizontal wires and such. Put a 160 resonator on top of that vertical. Use a low Q long skinny coil with a nice big capacity hat of 25 pico farads or so. It won't affect
