Vehicular Antennas . . .
Let ’em Stand at Ease
W
hen your vehicle’s parked for an
extended length of time, like over-
night, take the antenna out of the tie-
down clip and let it stand straight up.
This relieves the tension on the base
spring. Over time, tension weakens
the spring.
This also keeps the base spring coils
together, which helps keep out mois-
ture and debris. A tied-down antenna
has its spring coils spread open, mak-
ing it easier for dirt and moisture to
get inside and damage the base and
the RF cable.
ake the hookup between your
field expedient antenna and your
AN/VRC-12 receiver-transmitter
easy with the UG-1441 adapter,
One end of the adapter has binding
posts for field wire. The other end has
a BNC connector that fits the RT’s
ANT receptacle.
The wire from the adapter’s red bind-
ing post goes to the antenna. The wire
from the black binding post goes to
the counterpoise (lower wire).
To keep the adapter handy, fasten it
to the RT’s handle. This fix beats try-
ing to feed field wire directly into the
set’s receptacle.
