One of the most common faults with tv aerials is water ingress which can travel down the cable and as in this instance has blown the tuner on customers television.

Water ingress in your tv aerial can happen a couple of different ways, a cable flapping on the roof can become split or if the cable is old it looses its uv resistance and fails.

Another way is through the aerial when some aerials such as an antiference rx12 or most older triac aerials had a bowl where the cable was fed into which filled up with water and gravity did the rest.

If you are experiencing glitching or breaking up of signal on a wet day it maybe time to have your tv aerial checked, also check the coax plug to see if it is wet and if so remove from television and get in touch.
