Assembling/Adjusting
4
STEP
Antenna on Ground
On even ground, attach dish to the LNB Arm/Antenna B ack
Assembly as shown. Leave off the Triple-head LNB until the
antenna is mounted on the mast and you've routed cable
through the LNB Arm.
Set Tilt Adjustment
At the back of the antenna assembly, loosen the three Tilt
bolts and then set the Tilt adjustment according to the
coordinate number you obtained in S tep 1.
Tighten the Tilt bolts. Do not change the Tilt adjustment
again from this point on (even if you could not find the
satellite signal during alignment). Unlike the E levation and
Azimuth coordinates, there is no need to fine-tune Tilt;
doing so may cause alignment difficulty. For some of the
E astern S eaboard states, however, there maybe an
exception: see S tep 9, note #2, on page 10.
Set Elevation Adjustment
At the side of the antenna assembly, loosen the two Elevation
bolts and two Pivot bolts (one on each side) and preliminarily
set the Elevation adjustment, per the coordinate number
obtained in Step 1.
Tighten the Elevation bolts and Pivot bolts, but not completely.
This is a preliminary adjustment, which you may have to
fine-tune later on.

Attaching Antenna to Mast

STEP
S lide the back of the antenna assembly onto the top of the
mast until it stops. If necessary, slightly loosen the two
Azimuth/Mast clamp bolts so the antenna will go on to the
mast.
Tighten the two Azimuth/Mast clamp bolts and the pivot
bolt just enough so the antenna has only side-to-side
movement (rotational swing around the mast) for later
Azimuth alignment in S tep 9.

In this example we have
for Southern California
(ZIP code 92683),
the Tilt setting is 102 ° .
In this example we show
for Southern California
(ZIP code 92683), the
Elevation setting is 50 °
(use the position of the
metal edge to the Elevation
scale; do not use the washer
or the bolt as reference).
