C.4.1.2 LNA Feed Mount Offset Antenna Installation Instructions
To install a single LNA to an antenna:
1. Remove the protective cover from the antenna OMT and LNA.
CAUTION
After removing the protective cover(s), ensure that no foreign
material or moisture enters the antenna waveguide or LNA.
2. Install the appropriate gasket on the antenna end of the LNA.
a) If only one of the mounting surfaces has a groove, use the thin gasket.
b) If both mounting surfaces have grooves, use the thick gasket.
3. Position the LNA (with gasket) in place on the antenna OMT and fasten using the
#6 hardware from KT/2820 (8 each socket head screws, flat, split washers and
nuts).
C.5 Cable Installation
Care should be exercised in cable installation. Install the cables using the most direct
route and secure with clamps and ties. Avoid all sharp bends.
Cable connectors used in outdoor applications must be sealed to avoid leakage,
particularly N-type connectors. Moisture can seep into junctions at the plug end of the
connector, between the fixed and movable parts, and where the cable connects to the
connector. Signal attenuation and possible loss of signal can occur in the presence of
moisture. All cable junctions must be sealed with a self-amalgamating tape, such as 3M,
Type 23 Scotch Self-Amalgamating tape, or equivalent, including military style (MS)
connectors.
