MAINTENANCE
This antenna is constructed of heavy duty 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. This is
especially true in coastal areas where salty mist is commonplace.
E 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 connectors 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
marketed as "coax seal". This is 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 connector and the knurled area of the male connector. The bottom of
the male connector's outer sleeve should be left open to permit the connector to
"breathe". Mount the connector vertically with the unsealed barrel end down so
it does NOT collect moisture!
