Headend passive combiner consists of 5 to 1000MHz passive RF combiners designed for use in headend to combine the output of up to 32 single-channel devices such as modulators and processors. HPC is available in 8-, 12-, 24-, or 32-port models. All HPC models feature compact design, high isolation between ports, low net combining loss and RFI shielding for minimized egress/ingress interference. A front panel -20dB test port (75 ohms F type connector) allows testing of the unit’s output without interrupting the service.
