Mike:
Look back in QST CD's. There was a mobile antenna named "Texas
Longhorn" or something similar. If I remember, it was essentially two
antennae, one mounted on the front bumper and the other on the back
bumper, with an "element in between. Most of the radiation was
horizontally polarized. I don't remember details of how the thing was
fed.

p.s. Do participants in ILQP 2004 and earlier have experience which says
that 40 meters is "the band" for in state contacts? Based on MiQP and
OQP I'd be very skeptical, unless propagation conditions are very, very
different from those found in April and August. I made very few intra
state contacts on 40 or 20 meters during each of these contacts. If
80/75 doesn't open up by the time the contest ends, it would seem a very
difficult contest.

The pipe is mostly horizontal and terminates using a variable capacitor over the cab. The vari cap tunes the antenna over a wide range. Very rugged.
