SPECIFICATION

The UC-584S Top Mount Transponder Antenna Coupler solves the problem of reliable FAR Part 43 Appendix ‘F’ ERP (Effective Radiated Power) and transponder MTL (Minimum Trigger Level) testing in multi-path environments. The coupler is designed for use on the upper antenna and can be safely placed with a pole, eliminating the need to climb onto the fuselage and harness in for safety purposes. The UC-584S top mount coupler can easily be placed over the upper antenna from the ground or scaffolding, depending upon the size of the aircraft.
The UC-584 provides >20 dB of attenuation and minimizes the chance that airborne TCAS systems and air traffic controllers will see UUT transponder altitude replies under test conditions. The innovative design of the UC-584S includes an integral positioning slot, ensuring a high level of measurement repeatability is achieved, saving test time. The UC-584S can be connected to the VIAVI IFR6000, IFR6015, and APM-424 flight line test sets or to the VIAVI IFF-45TS bench test set, or to any suitable transponder test set.
