The UC‑584 Universal Transponder Antenna Coupler enables reliable FAR Part 43 Appendix F ERP and MTL testing in challenging multi‑path environments. It mounts directly over an aircraft’s transponder antenna using a secure toggle grip or can be slipped onto the top antenna when used with the top‑mount version. Providing over 20 dB of attenuation, it prevents airborne TCAS systems and controllers from detecting altitude replies during testing. Its integral positioning slot ensures repeatable measurements, reducing test time. The UC‑584 can also connect to standard test equipment for accurate, controlled transponder evaluations.
