The TC-201 TCAS / Transponder Directional Antenna Couplers build on the VIAVI industry-leading expertise in avionics testing equipment. This newest coupler is used on directional TCAS and combined TCAS / Transponder antennas to shield the RF signal during testing of the TCAS or transponder system.

The TC-201, when used with the IFR6000, IFR6015, or APM-424(V)5 supports maintenance testing in the airborne condition without interfering with air traffic control or nearby aircraft.

• Provides >20 dB of isolation
• Provides shielding for all transponder and ADS-B performance testing
• Lower antenna adjustable support pole
• Perform four-quadrant testing by simply rotating the bearing selector dial
• TCAS bearing accuracy < 10 degrees
