Digital television MMDS repeater equipment
2009/4/30
     There is a need to build repeater when the receiving station and transmitting station are far from each other or there have some blocked areas between them. The repeater does not need change frequency and has a high transmitting quality , which is the most economical and applicable relay station. It is usually used in the point-to-point relay stations.
The equipment also adapts to DVB-C, DVB-S, DVB-T (H), DMB-T, ADTB-T, and other international and domestic standard terrestrial digital microwave transmission and coverage systems.
