WAVE GUIDE RADAR (P/N at2-b-090-3) - Serviceable

The at2-b-090-3 is a waveguide radar component that routes high-frequency RF energy between aircraft radar transmitters/receivers and antenna arrays. This rigid or semi-rigid tube carries microwave signals in airborne weather radar systems, connecting the radar transceiver to slotted-array antennas. The waveguide uses standardized UG-series flanges per MIL-DTL-3922 for mechanical interface compatibility and secure RF coupling.

Installation requires verification of waveguide size and flange type against the aircraft's Illustrated Parts Catalog and avionics maintenance manual to ensure proper impedance matching and signal integrity.
