Antenna Installation and Alignment

Satellite Dish Installer: Ground the RF input cable to the building grounding system as

close as possible to the point of building entry. Refer to the National Electric Code (NEC)

Article 820-40.

The following steps describe the process to properly set up, position, and connect the

antenna using the DR500 Receiver:

1. Determine the proper block converter and feed horn polarity adjustment

for your area.

2. Assemble the satellite dish antenna.

Locate the antenna in an area with an unobstructed line of sight to the

satellite coordinates (azimuth and elevation) for your area.

4. For information relating to satellite location and coordinates, antenna

alignment, and signal acquisition, contacts your nearest DMX office.

5. Pre-position the antenna to the correct azimuth and elevation coordinates

by using a compass and inclinometer.

6. Pre-position the LNB to the indicated polarity setting.

7. Locate the DR500/1 Receiver within visual range of the antenna.

8. Connect a 75 ohm coaxial cable (RG-6, typical) from the output of the

LNB to the Receiver RF IN connector.

9. Connect 120 VAC power to the DR500/1 Receiver – do not turn it on.

10. Place the receiver in signal strength mode by depressing the power,

channel up, and channel down buttons simultaneously. Alternatively, this

may be done with the remote control using Preset 180. The display reads

nL, signifying it is not locked.

11. Channel 1 flashes on the front panel display indicating the receiver is

muted

12.

AUTH LED is Off unless the receiver is already authorized

13.

SYNC LED is Off and remains so until the satellite is acquired

14. The signal strength level numbers are preceded by a minus sign (-) to

differentiate them from a music channel number. Signal Quality readings

vary from -00 (the strongest level) to approximately -80 (weakest level)

before losing the satellite lock nL.

15. Rock the dish slowly from side to side and up/down around the nominal

position. When the Satellite has been located, the display will read out a

negative number representing signal strength and the Sync light will

illuminate. Carefully move the dish to maximize signal, at which time the

readout will be the least negative (closest to zero). Tighten the bolts and

check that signal strength has not been disturbed by tightening the bolts.
