3.5. 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.
RuggedCom recommends 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. RuggedCom does not recommend silicon seal or glue. These materials are difficult
to apply accurately and are difficult to remove. Do not use PVC tape.
3.5.1. 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. Ruggedcom recommends
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. If surge arrestors
are used, all the associated connections and arrestors must be completely wrapped with splicing
tape or self-amalgamating tape.
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 3.3. 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.
