Product Description
The 17-21 is a glideslope antenna for aircraft ILS navigation systems. This component receives vertical guidance signals in the glideslope band (329.15–335.0 MHz) and feeds compatible NAV receivers with glidepath data during instrument approaches. Typically mounted inside the nose radome or windshield, the antenna provides the vertical descent information pilots need for precision landings in low-visibility conditions.
Installation and testing must follow the aircraft's avionics manual and applicable FAA TSO/RTCA standards. Verify compatibility with your specific aircraft model before installation.
