Coax-Seal
Sealant

If you have any type of outdoor antenna you should be using Coax-SealŪ to protect any outdoor connection or connector. Coax-Seal is made of a non-conductive, non-contaminating waterproof substance that remains flexible at any temperature from -30° to 180°F. Coax connectors are not waterproof and exposed solder connections can deteriorate! Coax-Seal is superior to electrical tape or vinyl sealant for moisture protection.

One handy consumer box (60 inches x 1/2 inch) will protect nine connectors.
