Coverage Checkers


Note: These checkers are provided by the main telcos and give a broad indicator of where mast radiation readings are likely to be high. They work at the level of postcode, which could cover quite a wide area.


However, portable meters will pick up electromagnetic radiation from all sources, including possibly wi-fi transmittters on street lights and bus shelters, domestic routers and smart meters.
