Abstract :
The possibility of MMDS group TV signal transmitter creation is considered. The system of transmitting a group TV signal (up to 25 channels) in the MMDS range using one transmitter is known. The use of several one-channel transmitters instead of one group signal transmitter allows an increase in system reliability and repairability, lowers its cost and enables its introduction into operation in stages. The proposed method of using MMDS transmitters demands five antenna-feeders. That is the system´s weak point. On the other hand, if one channel transmitter fails, it does not affect the others. Block construction allows the failed block to be changed quickly without switching off the others.
