Weatherproofing

It is extremely important to weatherproof all outdoor cable connections. Weatherproofing the connections at the
outdoor unit and antennas prevents corrosion, prevents water from interfering with the connection, and helps to
keep the connection tight. Because cables also carry DC current, the need for proper weatherproofing cannot be
overstated.
We recommend the use of sealing tapes designed for outdoor use:
• 3M™ Scotch® Super 88 Electrical Tape
• Heavy-duty weather-, abrasion-, and UV-resistant rubber splicing tape or self-amalgamating tape
Rubber mastic putty or duct sealing putty must also be used to complete the weatherproofing where needed.
We do not recommend silicon seal or glue. These materials are difficult to apply accurately and are difficult to
remove. Do not use PVC tape.
Section 4.10.1.1

Weatherproofing Cable Connections

Most outdoor unit, antenna, or cable problems are caused by coaxial cable connections loosened by vibration,
allowing moisture to penetrate the connector interface. We recommend that all outdoor unit-to-cable connections
be weatherproofed using a procedure similar to the one described below.
This method of weatherproofing must be completed on all external connections, including RF connectors, RF
adapters and both sides of RF cables. If surge arrestors are used, all the associated connections and arrestors
must be completely wrapped with splicing tape or self-amalgamating tape.
NOTE
Before waterproofing, ensure all connectors are correctly tightened. Ensure the connector and cables
are free of foreign substances such as oil, water, grease, and dirt. Ensure that the cable extends below
the connector to which it is attached, providing a path for water to follow away from the connected
device.
Procedure: Weatherproofing Cable Connectors
1. Begin to wrap the rubber-splicing or self-amalgamating tape. Start as close to the equipment body as
possible. Stretch and wind the tape around the connector housing, ensuring there are no gaps in the tape.
