Technical brief
## Construction
8-inch cavity for VHF pass-reject filtering. Highest Q-factor in the VHF pass-reject series, sharpest notches with the lowest residual insertion loss.
## Where this fits
High-density public-safety sites, broadcast STL, paging, and repeater installations where rejection depth and selectivity drive sensitivity.
