WEATHER PROOFING COAX CONNECTIONS
1. Coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Care should be
taken not to get any lubricant on the center conductor.
2. Wrap the connector assembly with a vapor barrier patch for weather proofing (See Note 2), ensuring to overlap onto the coax
cable approximately 1 1/2 inches.
3. Apply a electrical coating (sealing agent) over the vapor barrier patch for added protection (See Note 3).

GROUNDING
All building mount antennas require attachment to a good earth ground for optimum efficiency. Contact a reputable local
communications shop for procedures for your area.
LIGHTNING ARRESTORS
Lightning arrestors should be used on all external building mount antennas for personal protection and to minimize damage to the
transceiver during lightning storms. The units should be installed as per manufacturers instructions provided with the device.
REFERENCE MATERIAL
The ideal reference book for antennas and transmission lines is the “The Radio Amateur's Handbook”, by the Headquarters Staff of
the American Radio Relay League.
