Key Takeaways:

  • The author upgraded an obsolete and failing Narco 50A transponder to a new Stratus ESG transponder system in their airplane.
  • The installation involved replacing the old rack and encoder with a new, more accurate encoder (25 ft accuracy), and drilling a new hole in the fuselage for a dedicated GPS antenna.
  • New antenna cables were carefully routed, and the Stratus 2S unit now integrates with the external GPS antenna, eliminating the need for a sky view.

Stratus ESG transponder and Stratus 2S

My new Stratus ESG Transponder and my Stratus 2S. The 2S is connected by an antenna and power cable inside an open bay in my panel. The Stratus 2S obtains satellite information from the newly installed GPS antenna, so it no longer has to have a visible view of the sky. However, it must retain the proper fore and aft orientation in order to provide the necessary attitude information.
