I have a copper J pole set for 2 meters and it works great. My radio is in a basement, but the run is just under 50 feet of lmr400. I often have a scanner running, but the reception is (as expected) horrible in the basement. I want to run a strand of rg59 up and mount a rubber ducky outside on the same mast as the ham antenna. The idea is to mount the rubber ducky on a short length of pvc that will sit beside (but not in contact with) the non-radiating portion of the jpole. Can anybody suggest why I might not want to do this? I can't imagine I would use both radios at the same time.
