The 12-Port Combiner is a Headend Equipment. Headend include several equipment such as head-end, rectifiers, digital satellite receivers, transmitters, RF modulators (QAM/QPSK), control modules, servers that receive the signal from satellites and after that, decode, encode, and multiplex the signal to send in fields via fibers to subscribers.
The HCG Series (12-port / 24-port) passive head-end combiners are designed to combine multiple RF inputs into a single RF output while maintaining high isolation between ports. The HCG Series combiners operate at a full 1 GHz passband.
