You did not say what your vertical radiator material is. Make it out of
wire (support it with PVC tubing), then you can put up 2 vertical radiators,
one for 20m, the other for 30m fed by the same coax. I guess this would be
a "Fan Vertical". Its based on a W6SAI design published in 1990. I've done
it with 10/15/20m radiators and it works well with elevated radials made
from TV rotator wire.

Good luck,

Hi,

For 20m I am planning a quarter wavelength vertical radiator with 4
eighth wavelength radials, mounted 12 feet high.

If I add another 4 radials cut an eight wavelength for 30m, will it be
easier to operate on 30?

Thanks,
