Viavi Aeroflex UC-584 Universal Transponder Antenna Coupler

UC-584 (Viavi / Aeroflex) Features and Specifications *

The Viavi UC-584 Universal Transponder Antenna Coupler is an innovative solution for reliable FAR Part 43 Appendix 'F' ERP (Effective Radiated Power) and transponder MTL (Minimum Trigger Level) testing in high multi-path environments such as ramps and hangars. This device ensures greater than 20 dB of antenna isolation for Mode S transponder altitude and diversity tests, with less than 1 dB repeatability. Its rugged design makes it ideal for ramp use, and it fits most 'Shark Fin' L-Band antennas, featuring a quick action antenna grip and release mechanism.

The antenna coupler directly mounts over the aircraft transponder antenna, secured in place with a toggle action grip. It provides 20 dB of transponder antenna isolation, ensuring that airborne TCAS systems and SSR ground stations do not detect the UUT transponder altitude replies under test conditions where the air-data system is pressurized to flight levels. The innovative design includes an integral positioning slot to ensure high measurement repeatability, thus saving test time. Additionally, the UC-584 can be connected to the Aeroflex/Viavi IFR6000 / IFR 6015 direct connect port, with its 1.5 dB insertion loss being compensable by adding this amount to the setup menu cable loss parameter.

In terms of specifications, the Viavi UC-584 operates at frequencies of 1030 MHz and 1090 MHz, with a return loss greater than 7.71 dB at both the antenna under test input and the coupler input. It has an insertion loss of 0.6 dB ±0.5 dB, repeatability of less than 1 dB, and isolation of more than 20 dB. The physical characteristics include dimensions of 5.25 inches in height, 5.75 inches in width, 8.25 inches in depth, and a weight of 2 lbs. The device features a TNC female connector, making it a versatile and essential tool for avionics testing.

The Viavi/Aeroflex UC-584 price and features make it a very attractive option compared to similar universal transponder antenna couplers available on the market.
