Step 4: Attach the mast clamp insert
Find the U-bolt and mast clamp insert (see

into the mast clamp insert with the teeth of
the mast clamp insert facing the closed end
of the U-bolt.
Insert the U-bolt into the mast clamp on
the antenna and loosely thread the 1/4”

the mast clamp and the teeth on the insert
should be facing the same direction.
Do not tighten the hex nuts yet.
