Vince:
What you're proposing is described in a CQ Magazine article, April
1987, page 66, entitled "An HF mini-dipole using mobile whips" by Bob Norloff,
w4gex. I'll send you a xerox copy by snail mail if you can't find a copy
there.
You can find a bar to connect the mobile whips together from :
Lakeview Co., Inc.,
3620-9 Whitehall Road
Anderson, SC 29626
(864) 226-6990.
I use such a set-up occasionally with my Argosy II while parked in my
pick-up truck. The mobile whips for 75 or 40 meters are mounted on top of a
16-ft. pole. This works fine for a 300 or 400 mile radius. I don't know how
it would work with the mobile whips for both bands mounted near each other on
the pole. But I would think at the spacing you propose, and operating one band
at a time, there should be no interaction. Or you might mount the antennas
for each band at right angles to each other.
GL and let me know if you're good in qrz.com.
