The UC-584S (TOP MOUNT) Universal 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 mounts directly over the aircraft transponder antenna(s) and is secured in place with a toggle action grip, or slipped onto the top antenna when using the top mount coupler. 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-584 includes an integral positioning slot, ensuring a high level of measurement repeatability is achieved, saving test time. The UC-584 can be connected to the VIAVI IFR6000, IFR6015, and APM-424(V)5 flight-line test sets or to the VIAVI IFF-45TS bench test set, or to any suitable transponder test set.
