MFJ-1792/1793 Instruction Manual
Vertical Antenna

MAINTENANCE
Your antenna is constructed of heavy duty non-corrosive materials and should withstand
normal climates for many years. The use of some type of coaxial connector moisture
protection is recommended at the bottom coax connection and also around the matching
network feed point, especially in coastal areas where salty mist is commonplace.
GE makes a pure silicone grease called "SILICONE DIELECTRIC COMPOUND" that
can be applied SPARINGLY to the threaded area of the female connector. This
compound, or even a clear silicone heat sink compound, will prevent moisture from
entering the connector through the threads and protect the connector from corrosion.
THIS IS THE SAME TYPE OF SEALER THAT COMMERCIAL ANTENNA
INSTALLERS AND CATV COMPANIES USE WITH GREAT SUCCESS.
A less desirable but adequate sealer is the automobile seam sealer commonly sold as "coax
seal," a pliable black sealing compound.
When installing any coax sealer, NEVER completely cover the barrel of the coax
connector. The sealer should ONLY be placed near the junction of the threaded part of
the chassis connector and the knurled area of the male connector. This will leave the
bottom of the male connector's outer sleeve open and permit the connector to "breathe" so
it does NOT collect moisture!
