Weatherproofing
Over the years many different methods have been used to weatherproof coaxial cable connections.
Some worked, some did not. Once water or condensation enters your coaxial cable, it will ruin the
coaxial cable or worse yet, cause shorting or high SWR conditions which could lead to permanent
damage to your transmitter.
One type of coaxial connector sealing material is a gummy tar like substance that you wrap around
the coaxial connector. This gummy substance works pretty good, except when you try to remove it
for maintenance or coaxial cable replacement, it can cause further problems. The gummy substance
just doesn't come off cleanly and small bits of it may remain in the threads of F Connectors, PL-
259's or SO-239's. These small bits of material are mini-insulators, and could cause intermittent
operation.
The method described here uses a combination of two types of tape which not only protect your
coaxial connection, but also allow easy removal for future maintenance.
Additionally, the coaxial cable and connectors should be clean and free of any moisture, dirt or
other residues.
The only tool you will need for this procedure is a pair of scissors. The following example shows an
F Connector being weatherproofed on a unit that will be used outdoors.
Note: The use of tape weatherproofing F Connectors that are outdoors and exposed to the
elements is up to the user. If Dielectric Grease is used, some people say this is enough
protection. Look at your cable TV installation - chances are there is no weatherproofing tape.
Others may want to go the extra steps for their own piece of mind.
A. Cut a piece of
TES-2155
- 3M Temflex™ 2155 Rubber
Splicing Tape long enough to complete the job you are doing.
If the length you cut is too short, that's okay. You can add more
where needed and it will not compromise the weatherproofing.
In this example a 4" length of the
TES-2155
- 3M Temflex™
2155 Rubber Splicing Tape was used to weatherproof the F
Connector that is installed on a unit
B. The
TES-2155
- 3M Temflex™ 2155 Rubber Splicing Tape
has a protective backing material so the tape will not stick to
itself when on the roll. As shown below, peel this protective
backing off of the length that you cut from the roll.
