ANTENNA. There are four methods to tie down an antenna: (1) stay-down clamp,
(2) snap-free clamp, (3) stay-down clip, and (4) snap-free clip.
STAY-DOWN CLAMP. Use the following method to tie down an antenna when it is
necessary that the antenna remain tied down when it hits a stationary object.
a.
Make sure that tip cap has been in-
stalled to the top tip of antenna ele-
ment.
b. Slide clamp/clip of tiedown to
middle of top antenna element. Make
sure antenna is secured under clamp.
c. Pull antenna down until it forms a 45°
- 60° angle with the ground. The dis-
tance from the tip cap to the ground
must be more than 7 feet.
d. Using rope, tie down to vehicle. Never
cross antenna elements when more than
one antenna is being used.
For best communication results, untie
antenna(s) when stationary. Let it
stand up straight.
SNAP-FREE CLAMP. Use the procedure above when it is necessary that the antenna
snaps free when it hits a stationary object. Refer to the following illustration.
