Technical brief
## Construction
Large 8-inch high-Q cavity tuned for the airband (112-137 MHz). Pass-reject topology delivers a sharp notch at the unwanted carrier while preserving the wanted carrier with low insertion loss.
## Where this fits
ATC ground stations and aviation repeater sites needing rejection of an adjacent or co-channel emitter without sacrificing receiver sensitivity.
