Have a Fiberglass roof 5th Wheel RV, and am looking for an HF Antenna
to use on it. Suggestions on installing a plus.
Thanks & 73

Buy and Autotuner, Ground it to the RV Frame, go to Costco and buy
a 10# Party Balloon Helium Tank, and some Balloons, and get yourself
a spool of #24 wire. Reel out 200 ft of wire, connect one end to the
Tuner Output and the other end to the balloon, let the wire feed up
inside a piece of 1/2" PVC Pipe, fixed to the Ladder on the back of the
RV, and let the balloon FLY. It will out preform ANY Vertical of any
size, even in a mild breeze.
