While raising the antenna, keep a constant pulling pressure away from the Tilt Base. This will
ensure that the pivot point bolt will not jump out of the pivot slot and cause the tilt mechanism to
bind up and bend the bolts.
Starting from the top of the antenna, walk it up slowly using an overhead hand-over-hand motion,
maintaining a slow and steady pace.
The antenna mounting channel must be kept in parallel alignment with the tilt-base plate to prevent
binding until it is positioned in the tilt-base. Once the antenna is vertical, lift and slide the antenna
to the left toward the tilt-base mounting pipe to allow the two parts of the tilt-base to line up and
drop down into the slots. Lightly tighten the top flange nuts on the tilt-base to hold the antenna.
Note:
As you raise the antenna to the vertical position, it’s important to
maintain the parallel alignment between the antenna mounting channel
and the Tilt Base backing plate to minimize binding. Make sure the lower
tilt-base bolts are never excessively loose before raising. They should be
first tightened securely and then backed off 1/4 to 1/2 turn. No more than
1/2 turn.
Once the antenna is fully raised, tighten the tilt base hardware (Top: two Nyloc nuts and two flange
nuts, Bottom: two Nyloc nuts.)
