Assembling/Adjusting
4
STEP
Antenna on Ground
On even ground, attach dish to the LNB Arm/Antenna Back
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 Tilt nuts
•
and then set the Tilt adjustment according to the coordinate
number you obtained in Step 1.
Tighten the Tilt nuts. Do not change the Tilt adjustment
•
again from this point on (even if you could not find the
satellite signal during alignment). Unlike the Elevation and
Azimuth coordinates, there is no need to fine-tune Tilt;
doing so may cause alignment difficulty. For some of the
Eastern Seaboard states, however, there maybe an
exception: see Step 9, note #2, on page 10.
Set Elevation Adjustment
At the side of the antenna assembly, loosen the two Elevation
•
nuts (one on each side) and preliminarily set the Elevation
adjustment, per the coordinate number obtained in Step 1.
Tighten the Elevation nuts, but not completely. This
•
is a preliminary adjustment, which you may have to
fine-tune later on.

Attaching Antenna to Mast
STEP
Slide the back of the antenna assembly onto the top of the
•
mast until it stops at the pivot bolt. If necessary, slightly
loosen the two Azimuth/Mast clamp bolts and pivot bolt 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 Step 9.
Dish attaching to the LNB Arm/Antenna Back Assembly
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).
