Technical brief

## Construction
5-inch cavity tuned for VHF pass-reject filtering. Sharp notch on the rejected carrier while passing the wanted carrier at low insertion loss.
## Where this fits
Repeater sites with adjacent-channel emitters, dense urban deployments where intermod products need active rejection.
