HC Deb 04 March 2004 vol 418 cc1054-5W
Mr. Gibb

To ask the Secretary of State for Culture, Media and Sport what measures she is taking to tackle problems caused to television reception as a consequence of transmissions by TETRA masts.[158566]

Estelle Morris

TETRA systems in the UK are licensed to operate on frequencies within the bands 380 to 385 MHz; 390 to 395 MHz; 410 to 430 MHz; 871 to 876 MHz and 916 to 921 MHz. Television broadcasting operates on channels outside these bands; within the range 470 to 862 MHz. Interference should not therefore occur to TV reception from TETRA transmissions provided that the TETRA systems are operating in accordance with their licence conditions and the standard of installation of the TV receiver including its aerial system are satisfactory.

Ofcom, the independent regulator of communications is responsible for managing civil use of the radio spectrum including the investigation of legitimate reports of television and radio interference. Ofcom has published information on improving radio and TV reception to avoid interference, including specific advice on cases involving TETRA. In all such cases reported to Ofcom to date, the problems have been attributable to the performance of the consumers own TV aerial amplifiers which have been found to have a pass band wide enough to boost the TV signal and, inadvertently, the TETRA signals. In most cases a suitable filter between the amplifier and TV aerial will resolve the interference. Consumers in these cases have been advised to take up the problems with their suppliers.
