Assembling/Adjusting

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).
