it is likely one of the factors most known but at the same time one of the main sources of problems in a real tv installation subject to the weather conditions.

  • the water can easily flow through most of the coaxial cables used by the installers all over the world.
  • once inside the coaxial cable, the water is piped directly to the device thus broken it.

very typical are the lnbs received for repairing flooded because of the water, headends and amplifiers broken because of the water…

no matter if the headend/device is inside the building if the water can reach it just following the excellent way provided by a non-watertight coaxial cable.

see the next pictures:

picture 1

shows how the water has reached the f connector of the amplifier just using the perfect duct provided by the coaxial cable construction.

in picture 2 it can be seen how the water, once inside the device, can damage the circuitry up to the limit of burnt it, as shown in picture 3

the use of a non-watertight coaxial cable no longer is a problem whenever the end of the cable subject to the weather is perfectly sealed.

even though there can be found many brands of watertight coaxial cables, their use is not very common because they are much more expensive than the standard ones.

the use of watertight coaxial cables increase the cost of the installation and their use can be avoid by professional installer sthat know the rules to achieve a good installation free of problems.

the best way to do it is make use of amalgamating tape.
this tape is placed overlapped all around the connector and coaxial cable end.

after a time the tape amalgamates thus becoming a solid compound preventing the ingress of water into the coaxial cable or the connector.
