Why this product

  • 01

    6 BR cavities — 300 W continuous duty

  • 02

    Broader passband than BPBR variant for wider Tx-Rx separation systems

  • 03

    Same compact 9 kg chassis as the BPBR sibling

Technical brief

All-band-reject UHF

6 BR cavities for 300 W continuous-duty UHF operation. 60 dB suppression at the 4 MHz mark across a 10 MHz window — broader passband behaviour than the BPBR variant.
