Installing the radio assembly
To mount the radio assembly to the feed support arm:
1.
Position the radio assembly above the feed support arm so the feed horn
faces the reflector, as shown in
Figure 12
.
Note:
Never mark the radio housing or feed horn. Marks cannot be removed
and will result in the unit being scrapped if it is returned to Hughes.

2.
Guide the two tabs on the underside of the radio assembly into the bracket on
the end of the feed support arm so they fit into the guides on the inside of the
bracket, as shown in
Figure 13
on page 30. Be sure the toothed key on the
bracket fits into the slot on the underside of the radio, as shown in the
Figure 13
.
Note:
The support arm bracket key
must
fit into the radio slot. If it does not,
the radio will be unable to transmit to the satellite correctly.
If you lose the screw that secures the radio to the feed arm, find a
replacement screw of the same size.
Do not
drill any additional holes in the
radio or try to use a screw of a different size. Radios with additional holes in
the mounting tabs must be scrapped if returned to Hughes. Have spare nuts,
bolts, or screws on hand in case you lose those provided in the kit.
