I contacted Richard and Dave at Naylors Aerials after I had a problem with my reception. I explained that my picture was breaking up and they called to see me. Before being recommended to try Naylors Aerials by a friend at work I had contacted another local aerial firm who tried but failed to sort my picture problem. After doing some tests with there equipment a quick and positive result was formulated. It turned out to be interference from a mobile phone mast on what Richard said was operating on the new 4g system. He fitted a small metal filter and the reception is now perfect. I can positively recommend this firm 100%
