I can confirm that Rick's comment about missing street
carlines relates to the only reason we ever bent our
hut truck antennas during the "peace action" was to avoid
overhead obstacles or excess waving while moving (g) "Road surfaces" left
a bit to be desired and replacements were sometimes hard to find. Most of
the time we'd just remove
the whip to play it safe. When parked and in service they
were vertical. Our comm trucks were only used in support
of another comm hut truck with some specialized gear used
to find who on the other side was where. We used wire
antennas when possible during long term stationary ops which were
necessary to accomplish our work. Our receiving antennas were really fancy
for the
second truck (g)

Bill,
I suspect the 6dB increase in gain was due to the horizontal component
radiated when the antenna was bent over, not because it was grounded.
Being in Signal Corps and stationed in Berlin, I can tell you the main
reason we had our whips bent over was to keep them out of the high voltage
lines of the street cars!
What I taught the guys to do when they wanted more reliable communications
was to find a place to stop, about 30 ft. from a tree, remove the top two
sections of the whip, and screw in the whip-to-wire adapter, then string a
horizontal wire.
The inverted-L significantly outperformed the whip.
Actually the inverted ought to be the antenna of choice for many people,
because it has a vertical component for DX and a horizontal component for
NVIS.
Most people have forgotten (or never knew) how well this antenna can
perform.
