Technical brief
High-isolation UHF
Six cavities at 5-inch diameter delivers > 95 dB suppression in the UHF band at 5 MHz separation — exceptional even for the BPBR topology. The 482 × 266 × 380 mm chassis is compact (9 kg total), suited to dense rack environments.
Where this fits
UHF voice repeaters at 5 MHz Tx-Rx separation, especially in dense tower environments where extra suppression margin is welcome. Public-safety and commercial UHF repeater builds.
