Just wondering if anyone actually has tried using an unun for their mobile vertical antenna? I would like to use either my 75m hustler or my Eagle one push up. Coax fed . (Both mounted to the ladder on the rv ) As I understand verticals on vehicles have a very low impedance which makes them difficult to tune. I don't operate on the road and when in rv parks the real estate is somewhat limited, so ground radials are not very practical when only staying for a few days. Any thoughts appreciated.
