NSTALLATION
Refer to Figure 2-9.
Care shall 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 outdoors application shall 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 shall be sealed with a self-amalgamating tape, such as 3M,
Type 23 Scotch Self-Amalgamating tape, or equivalent, including military style (MS)
connectors.
WARNING
The Downconverter RF input connector is wired to supply DC voltage to an LNA.
This voltage is capable of damaging any test equipment connected to the connector.
Do not connect test equipment to this connector without a coaxial DC block between
the connector and the test equipment.
