Technical brief
## Construction
Single 8-inch high-Q cavity bandpass tuned for the airband. Provides clean selectivity with > 14 dB return loss across the operating window.
## Where this fits
Pre-filter for airband receivers in moderately dense RF sites, when a full duplexer is overkill but front-end protection is essential.
