Rick,
I've tried verticals on 75, and in my opinion, they're not worth wasting
time on unless they're designed to operate on that band. Even if you can
get the SWR down to 1/1, all you'll be doing is feeding the coax, and the
signal (or at least most of it) won't even reach the antenna. The bottom
line: you won't get out, and you won't hear much of anything but man-made
noise.
