Technical brief

Four-channel hybrid

Same hybrid topology as the UHF 3-Channel Hybrid Combiner with one additional channel. The fourth channel adds another 3 dB stage — IL rises from 6.2 dB to 7.5 dB.

Solves these problems

Combining multiple UHF transmitters onto a single antenna

Tower owners and operators need to host multiple transmitters on one antenna without sacrificing transmit power or generating intermodulation products.
