Helpful advice on when there is a need to call out a TV Aerial or Satellite TV Engineer to fix issues with our Television picture or sound.
Upon arrival give the aerial installer an explanation of the problems with the TV picture or sound. The engineer will then run through a list of tests which will help to find the cause of the fault, if it isn’t glaringly obvious (i.e the aerial has come down off the chimney in a storm). Using a spectrum analyser he will run a test on the coax cable to find out what the signal strength is coming from the aerial. The test will help to determine if the fault is from either the aerial head or antenna or possibly cable, or if it is an issue with interference from such things as WIFI routers. Finally it will point to a problem with either an amp, masthead amp power supply or even to the TV itself. The most common fault is due to the adverse weather conditions experienced in the UK.
For instance in TV Aerial Installation Preston can come under a lot of corrosive weather conditions due to the location being near the sea. This causes rapid corrosion of the aerial, its mast and bracket & also to the coax cable. Once the aerial head is compromised then water will enter and cause a shorting of the system which will result in problems with the TV picture through to complete loss of signal altogether. When this happens, then there is no possible way to repair the system, and a good engineer will offer a TV Aerial Installation for the full system. This should come with a guarantee and if the engineer is using cai or Rdi approved equipment, then you can have full confidence in the installation.
