2.5.4 Protecting Connectors

If connectors are to be exposed to a wet or humid environment for extended periods of time, protect the exposed

connectors as follows:

a. Silicone Grease (Dow Corning DC-5 or Similar Corrosion Preventative Compound)

Coat all ground connections with silicone grease or an equivalent dielectric compound. Apply a coating

approximately 1/8-inch (0.32 cm.) thick. This coating will prevent deterioration of the antenna

connection and its associated hardware. This will also protect the insulator from conductive

contaminants that could degrade the insulating properties of the connector system, such as oil, dirt, dust,

and corrosive material from the atmosphere. This is especially important in a salt-laden air environment.

b. Electrical Tape (3M Company 33+, Permacel 29R or similar)

Wrap connectors exposed to weather with several layers of weather-resistant electrical tape or similar

product (3M Company 33+, Permacel 29R). Wrap the tape as close as possible to the case, and far

enough up the cable to prevent moisture from contacting any part of the connector.
