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.

Key Takeaways:
- The author upgraded their airplane's failing and obsolete Narco 50A transponder and encoder to a new Stratus ESG system, installing a rack that fit the old location and a new encoder with improved 25 ft accuracy.
- A new GPS antenna was carefully installed on the fuselage, requiring drilling a new hole, strengthening the installation with a doubler, and sealing it to ensure leak-free operation.
- New antenna cables were routed from the GPS antenna and a whip antenna to the Stratus ESG transponder and integrated Stratus 2S, allowing the 2S to receive satellite information without needing direct sky visibility.
