Comant CI-1125-TNC Diplexer Single Nav VOR / LOC / GS Input To Dual VOR / Loc

The Comant CI-1125-TNC is a dual VOR/dual glide-slope diplexer for distributing signals from one VOR/LOC and glide-slope antenna to two VOR and two glide-slope receiver inputs. It is intended for avionics installations requiring separate NAV signal inputs from a common antenna system.

This CI-1125 variant is supplied in the TNC connector configuration and is designed for internal aircraft mounting. Its aluminium housing provides a compact, durable solution for NAV signal distribution within the avionics installation.
