Transmitting Stations

The following pages describe the coverage areas of the ITA’s transmitters, the varied problems which the Authority’s engineering staff have had to overcome in bringing Independent Television to each area of the country, and the technical details of the stations. The maps show the reception which should be available from each transmitter, on the following definitions:

PRIMARY SERVICE AREA

Within 2mV/m median contour


Where most viewers unless they are situated in particularly unfavourable positions should receive a consistently satisfactory service.

 

SECONDARY SERVICE AREA

Within ½mV/m median contour


Where a substantial proportion of viewers should receive a satisfactory service, but in a few unfavourably situated places reception may be poor.

 

FRINGE AREA

Within ¼mV/m median contour


Where acceptable reception should be secured in many locations, although this service may be subject to some interference from time to time. Some viewers living in favourable positions outside the Fringe Area may also receive a satisfactory service.
