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.
After removing the protective cover(s), ensure that no foreign
material or moisture enters the antenna waveguide or LNA.
CAUTION
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.
