Q: What are the STX 165 and STX 165R power requirements?
— Asked on July 23, 2014
A: Both the STX 165 and STX 165R (Remote) are designed to operate from 11-33Vdc. Current consumption is dependent on three factors: 1) Squawk Code. The higher the squawk code the more pulses that are transmitted. More pulses require more current. 2) PRF (Pulse Repetition Rate). Like the squawk code, the higher the PRF rate the more current a transponder will draw. 3) In the case of the STX 165 that has a built-in encoder current increase when the encoder heater is on.

Q: What does 1/2 3ATI cut out mean?
— Asked on July 23, 2014
A: A 3ATI is a 3" Airline Transport Indicator size cut out. 1/2 is exactly that. It is the 3ATI form factor but only half height. Sandia uses this form factor because it is both an industry standard and has a professional appearance.

Q: What is the Strobe Line?
— Asked on July 23, 2014
A: Older transponders"Strobed" encoders whenever they wanted an altitude update. This is not required in newer transponder systems. When the STX 165 altitude output is being used by another system that does not require a strobe, a ground on the STX 165 Strobe line is usually required.

Q: What is the SMA Connector?
— Asked on November 28, 2014
A: The SMA connector is a standard aviation industry connector. If you do not have a SMA crimper it is suggested that you contact a local avionics shop. Stein Air (www.steinair.com) fabricates harness to your custom length. You can also use an SMA to BNC adapter but you might experience some dB drop in signal.

Q: Is this unit ADS-B compatible?
— Asked on November 28, 2014
A: Sandia STX165 Mode C TRANSPONDER with a UAT / WAAS GPS will meet the 2020 ADS-B mandate when interface with a compatible UAT transceiver. The STX currently interfaces with MGL, uAvionix and the Garmin GDL 82 to provide a compliant solution. When installing ADS-B the FAA recommends against installing both 1090 ES (Mode S) and UAT as they can conflict with each other and transmit your aircraft position twice.
