Key Takeaways:

  • The article details the replacement of an airplane's obsolete Narco 50A transponder and encoder with a new Stratus ESG transponder and a high-accuracy encoder.
  • A significant part of the upgrade involved the meticulous installation of a new external GPS antenna on the fuselage, requiring drilling, strengthening, sealing, and precise placement to avoid signal shadowing.
  • This upgrade integrated the Stratus 2S unit, allowing it to receive enhanced satellite information from the newly installed GPS antenna, thereby improving the aircraft's ADS-B capabilities.

My original transponder installation in my panel. A Narco 50A. The transponder worked fine when I bought the airplane two years ago, but it was failing and obsolete. It was not worth repairing.
