< 20 MHz channel spacing — tighter than any cavity combiner
03

Compact 1U-equivalent chassis (132 mm tall)

Technical brief

Hybrid topology

Resistive hybrid combining trades insertion loss (6.2 dB) for very high isolation (> 100 dB) and the ability to combine carriers within a 20 MHz window — much tighter than cavity combiners. Suited to broadband multi-channel deployments where cavity tuning is impractical.

Frequency option blocks

Factory-tuned to one of: 380-400 / 400-420 / 420-440 / 440-460 / 450-470 MHz.

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.
