Installation

To install a single LNB:

1. If installed: Remove the protective covers from the LNB and TRF.

CAUTION

After removing the protective covers, ensure that no foreign
material or moisture enters the antenna waveguide or TRF.

2. Install the appropriate o-ring on the LNB or TRF, as follows:

a. If only one of the mating flanges is grooved, the thin o-ring should be

installed.

b. If both of the mating flanges are grooved, the thick o-ring should be installed.

3. Position the LNB (with o-ring) in place on the antenna OMT and install with

provided M4x12 socket screws and No. 8 SAE washers (split and flat).
