needed antenna design is for 80M, operation only while stopped, must be
vertical, and lastly, must not require me to climb up to the RV rooftop
to put it up or take it down. I have a good idea where I'm going with
this and will discuss the final product when it is completed ... probably
several weeks from now.

At one of the CA 75m shootouts, Sanford, W6YY had
a motorized 30 foot vertical mounted on top of his
huge RV. While he was traveling, it laid down against
the top of the RV. When he was stopped, he had it
motorized so he could raise it to a vertical position.
He beat the best of the best 75m mobile bugcatchers
and screwdrivers by 2 dB and beat a 75m hamstick
by about 14 dB. It's certainly worth considering.
