The majority of time (and
always in garrison) the antenna
should be in the stay-down slot of
the clip or clamp. You do not want
the antenna bouncing free and
striking a power line or other over-
head obstruction.
However, the stay-down position does have its own safety prob-
lems. If you hit an obstruction with the antenna locked down, the
antenna will shatter and could cause serious injury from flying parts.
So, if you are operating in the field away from all overhead
obstructions except trees, you can put the antenna in the snap-free
position. That way, if you hit a tree limb, the antenna will spring up
and not break.

As a rule of thumb, though, the safest and by far the most used
position should be the stay-down one.

Vehicular Antennas…
Dear Half-Mast,
We use both the clamp and the clip to hold down our AS-3900 and
AS-1729 antennas. My question is, when do we use the stay-down
position and when do we use the snap-free position on the clamp and
the clip?
Pvt D.L.A.
Dear Private D.L.A.,
Even though it decreases your radio’s range
with the antenna tied down, you should keep a
vehicular antenna tied down when you are on the
move. Having the antenna waving in the air
greatly increases your risk of hitting a power line
or an overpass.
We’re using
the stay-down
position on our
vehicle…
well, We’re
using the snap-
free position
on ours.
which
one is
right?!
This
is why
you tie your
antennas
down!
On the move?
Tie it down!
Beware
power
lines
Stay-down
position is safest
and most used
