Delivers Improved Safety With Increasing ADS-B System Testing

Viavi Solutions Inc. has announced its UC-584S Top Mount Antenna Coupler to provide isolation and shielding for consistent aircraft transponder testing in ramp and hangar environments without signal interference. The UC-584S is designed to be quickly and safely installed without requiring personnel to climb onto the aircraft fuselage. This new solution will be unveiled on March 25th during the New Product Introductions session of the AEA International Convention.

With the transition to the FAA's NextGen air transportation system, there is an increased focus on improving safety and efficiency, including implementation of the Automatic Dependent Surveillance – Broadcast (ADS-B) system. As the January 1, 2020 deadline approaches to install ADS-B Out transmitters in order to fly in controlled airspace, the accelerating pace of ADS-B installations is giving rise to significant growth in performance testing. Because these systems must be tested in the airborne condition, the use of antenna couplers are required to shield the signal and prevent interference with Air Traffic Control or other aircraft.

Viavi developed the UC-584S antenna coupler to be easily placed over the top L-Band "shark fin" transponder antenna using a pole, either from the ground or atop scaffolding, depending on the size of the aircraft. This eliminates the need for installation personnel to wear a harness and climb onto the fuselage, for safer and more streamlined testing conditions.

"With our deep expertise in avionics test equipment for verification and maintenance of commercial and military systems, Viavi delivers innovative solutions that provide reliable, repeatable test results in high multi-path environments," said Guy Hill, Director of Avionics Test Products for VIAVI. "We understand that ADS-B testing is a priority for improving overall safety and efficiency, and our focus is to enable proper testing procedures for efficient collection of the critical data required to ensure a safe flying environment."
