Using a wrench or nut driver, securely tighten the two Nyloc nuts at the bottom of the Tilt Base.
Then loosen them one-half turn each. This will allow proper movement of the Tilt Base while
raising or lowering the antenna. It is not necessary to tighten these nuts more securely unless further
tilt operation is no longer required. They should not be loosened more than one-half turn at any
time.
Test the tilt function to ensure proper clearances. Standing in front of the Tilt Base, lift the antenna
base section, slide it to the right, and let it down slightly until the lower outside bolt is resting in the
pivot point. Then slowly tilt as shown in
Figure 9
. Make sure when you are tilting the antenna to
lift, slide to the right
, and
then
tilt. Be careful to keep the pivot bolt resting in the pivot point.
Reverse the process when raising the antenna.
It is important to note that the lower, outside bolt becomes the pivot point while raising or lowering
the antenna. This pivot bolt
MUST
be retained in the pivot point. It seems natural to
push
the
antenna toward the Tilt Base while raising.
Push up
while raising, but not toward the base since this
could cause the pivot bolt to lift out of the slot and allow the mechanism to bind up and bend the
lower bolts.
The Tilt Base is not made to support the whole antenna
by itself when tilted. When the antenna is tilted over,
ensure you have some sort of table, stand, or saw horse
to set the antenna on to aid in supporting the weight.
When the antenna is in the upright position, ensure the
mounting hardware (reference
Figure 8
) is tightened.
Figure - 9 - Tilt Action
The antenna is mounted to the front of the Tilt Plate.
(This picture shows the antenna as if you could look through it to see the grooves in the
tilt plate. You can see a partially tilted antenna in Figure 15).
Note:
A pair of sawhorses or ladders should be used to support the vertical sections during
assembly with the tilt-base and whenever the vertical is tilted down. Do not allow the
Tilt Base to support the entire weight of the vertical when horizontal.
