Horwin Hybrid Transmitter Combiners

Horwin CH-V/Ux-x series is a VHF hybrid combiners with ferrite isolators used for combining several VHF transmitters into one antenna with close frequency spacing. Combiners are configured in sets of 2 or 4 channels.

There are two model versions – single or dual ferrite isolators depending on the required Tx – Tx isolation and (or) low/high power. Nominal impedance is 50 Ohms. N-type “female” connectors are used for input/output connections.
Combiners are mounted on standard EIA 19” panel 3 U high and 355 mm depth.

Combiners are tuned at customer specified frequencies, so transmit frequencies should be specified when ordering.
