Abstract :
Due to topographical conditions areas often exist inside the service area of a television station where the field strength is inadequate for normal domestic receivers to operate. Apparatus is described which, mounted on high ground, can receive the programme and convert it to another frequency and re-radiate it into these areas. Regions beyond the service area of the television transmitter can be served by using a combination of a link system and a booster transmitter. For those areas where locally generated programmes are required for certain periods, apparatus for feeding in video and audio signals is described.
