Antenna Couplers
Aeroflex Test Solutions (VIAVI)
Cobham AvComm manufactures a series of Antenna Couplers designed to solve the problems associated with over-the-air testing. Here are just some of the benefits gained from isolated (coupled) testing: Reliable effective radiated power Reliable power and minimum trigger level testing Prevents uninhibited transmissions Prevents interference with ATC operations Eliminates need for frequency authorization

Antenna Coupler Kit
F-16 IFF
-
The new Cobham AvComm F-16 IFF Coupler Kit provides isolated IFF Interrogator and Transponder testing to eliminate the need for DD-1494 frequency authorization. It solves the problem of over-the-air testing resulting in unreliable radiated power and transponder minimum trigger level testing in a high multi-path ramp and hangar environment.

Universal Transponder Antenna Coupler
UC-584
-
The UC-584 Universal Transponder Antenna Coupler is 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 UC-584 antenna coupler provides 20 dB of transponder antenna isolation, ensuring airborne TCAS systems and SSR ground stations do not see UUT transponder altitude replies under test conditions where the air-data system is pressurized to flight levels. ADS-B transponder antennas exhibit gain in the forward direction, which adds to the complication of where to position test antennas in relation to the aircraft antenna to achieve a repeatable ERP test. The innovative design of the Antenna Coupler includes an integral positioning slot ensuring a high level of measurement repeatability is achieved, saving test time.

CNI8 Antenna Coupler Kit
UC-233
-
The new Cobham AvComm UC-233 IFF Antenna Coupler Kit was designed for use with the CNI8 family of multifunction UHF/L-Band antennas found on multiple military aircraft platforms. Isolated testing solves the issues of unreliable radiated power and transponder minimum trigger level in a high multipath environment when performing over-the-air tests.
