Technical brief

## Construction
Compact 5-inch high-Q cavity tuned for VHF bandpass. Light enough for tight installations, capable enough for 300 W continuous duty at 0.5 dB insertion loss.
## Where this fits
VHF voice repeater receive paths, marine band, industrial, and where 5-inch form factor matters more than the extra Q-factor of larger cavities.
