Used / Serviceable Viavi UC-584DUAL - Universal Transponder Antenna Coupler

The Used / Serviceable Viavi UC-584DUAL Universal Transponder Antenna Coupler is a highly effective tool designed to solve the challenges of reliable FAR Part 43 Appendix ‘F’ ERP (Effective Radiated Power) and MTL (Minimum Trigger Level) testing in multi-path environments. Ideal for use in aviation, this versatile coupler is engineered to provide more than 20 dB of attenuation, reducing interference and ensuring accurate test results for transponder altitude replies during testing.

The UC-584DUAL is specifically designed to mount directly over aircraft transponder antennas, with a quick-action toggle grip for secure placement, or it can be used as a top-mount coupler for larger aircraft. It fits most "Shark Fin" L-Band antennas and is designed for use with Viavi IFR6000, IFR6015, APM-424(V)5 flight-line test sets, or any compatible transponder test set.

With a rugged design suited for ramp use and a dual-antenna configuration, the UC-584DUAL minimizes the possibility of false intruders and interference with air traffic control systems while enhancing the repeatability and efficiency of test measurements.
