HFH2-10 – 2 x 10kW HF Broad Band Hybrid Combiner

The HFH2-10 series of broad band hybrids enable two co-phased 10 kW transmitters to be combined into a single 20 kW output. These units are particularly useful in low power HF broadcast systems where uninterrupted service is required when failure in one transmitter occurs.

Due to the excellent isolation characteristic of the HFH2-10, combination of two unequal frequencies for common antenna working is possible if the 3 dB power loss can be tolerated.
