Installing the radio assembly
To mount the radio assembly on the feed support arm:
1.
Position the radio assembly above the feed support arm so that the feed horn
faces the reflector, as shown in
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 that they fit into the guides on the inside
of the bracket.
Be sure that the toothed key on the bracket fits into the slot on the underside
of the radio, as shown in
on page 35.
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.
Position radio so
feed horn points
toward reflector.
