Transponder Antenna Coupler

Transponder Antenna Coupler

The UC-584 Series Transponder Antenna Couplers are designed to solve the problem of reliable FAR Part 43 Appendix ‘F’ ERP (Effective Radiated Power) and transponder MTL (Minimum Trigger Level) testing, in the high multi-path ramp and hangar environments.

The innovative design of these couplers include an integral positioning slot ensuring a high level of measurement repeatability is achieved, saving test time.

    • The UC-584 clamping mechanism is ideal for securing the coupler to the bottom antenna.
    • The UC-584S allows the operator to safely place the coupler onto the top antenna from the ground or ladder, using a pole, eliminating the need to climb on top of the aircraft.
