The HFH2-10 series of broadband 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, a combination of two unequal frequencies for common antenna working is possible if the 3 dB power loss can be tolerated.
