The UC‑584S Top Mount Transponder Antenna Coupler enables reliable FAR Part 43 Appendix F testing of Effective Radiated Power and Minimum Trigger Level in challenging multi‑path environments. Designed for placement on an aircraft’s upper antenna using a pole, it eliminates the need to climb onto the fuselage, improving safety and efficiency. It provides over 20 dB of attenuation, reducing the chance that airborne TCAS systems or air traffic controllers will detect altitude replies during testing. Its innovative design allows easy positioning from the ground or scaffolding, depending on aircraft size, ensuring accurate and controlled transponder testing.
