Usually a call out to a TV Aerial Fitter results from problems with the signal from your Television aerial installation expert. The type of problems can range from picture break up on some if not all channels, loss of sound, picture freezing and glitch, through to loss of picture and complete loss of signal. There are some simple checks that can be carried out, but after these have been done with out success, then it really is time to call in the experts.
Knowing which engineer to pick from off the internet can be difficult. The websites will vary from site to site. It can be a little confusing to say the least, but what can help is to read some of the inof on the website. Does this engineer offer helpful advice? Are they registered as members of either the cai or Rdi? Is there plenty of content relating to your TV Aerial Repair, and are they local, for an example of a good site is TV aerial installation Blackpool . This site nicely explains what services they offer and also goes into other areas of services they include. As well as TV Aerial Installation & Repairs, they are also Sky Installation & Freesat Installation engineers. They offer TV Wall mounting services too so this aerial fitter seems to cover a good range of related services for the home.
When you have decided on which engineer to call, it is worth finding out a ball park figure as to what a repair is likely to cost. Some will try to dodge this question, but a good aerial installer will be helpful enough to give you a possible figure of firstly a call out charge, an average aerial repair cost and a complete TV Aerial Installation cost, so that it sin’t going to be a wasted journey for the engineer.
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 analyzer 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 or bluetooth adapter. 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.
