Stratus ESG Transponder

Stratus ESG Transponders are TSO-certified* transponder that provides compliance in one box. It’s a 1090 MHz extended squitter (ES) transponder with built-in WAAS GPS.

Appareo ADS-B In Out Transponder

Designed to replace legacy transponders, Appaereo ADS-B In Out Transponders are solid-state transmitters that provide 310 watts nominal power output. Its modern keypad makes entering a squawk code easy. The convenient VFR button minimizes pilot keystrokes.

Stratus ESG ADS-B Transponder Integrations

Stratus ESG ADS-B Transponder is a form-factor replacement for existing transponders — such as the popular KT 76A/C** — so installation is more time-efficient compared to remote boxes that need to be integrated with your old transponder.

For those who have already invested in a WAAS GPS the Stratus ES is also compatible with the following:

  • Garmin 430W, 530W, 650, 750
  • Avidyne IFD440, IFD540

Stratus ESG Transponder Antenna Included

A TSO’d WAAS GPS antenna is included in the kit, and Stratus ESG can reuse an existing transponder antenna. It also accepts both serial and parallel (e.g. Gray code) inputs, so you can reuse most altitude encoders.
