Mobile Television Radio Link

摘要

The new radio link is intended for the transmission of signals of a television image (black-white and color) and a two-program sound accompaniment. The radio link can be used both during operation with mobile television stations and with fixed variant (SRL-11). This is necessary, for example, for the transmission of signals of television and sound accompaniment in the case of a separated variant of the television center (the ASK and RPS are located at separate sites); for the transmission of signals to television relays by means of branching from radio-relay main line; for television relay points (from theaters, palaces, concert halls, videotelephones, etc.). The equipment of the radio link ensures the steady transmission of signals for a distance up to 50 km without an intermediate relay at any time of the year and day with the compulsory absence of obstacles in the Fresnel zone and a power of l W for the radio transmitter. The equipment of the radio link operates in the frequency ranges of 7550-7750 and 8500-8700 MHz, in which 10 radio channels are found. The number of radio links operating simultaneously is six. The radio transmitters of the radio link can be removed up to a distance of 300 m from the transmitter control and power supply units.
