The system chart of receiving and transmitting interface

System Instruction

The system works in 4.6G frequency range, transmitting the same steam from local side to distal end in 1+1 hot backup mode with different frequency and different direction of polarization.

The distal end receiving equipment modulates 2 channels of same stream and sends to stream signal decision device. Under the premise of a least 1 normal radio frequency channel, it always keeps one channel of normal stream output.
