Key Takeaways:

The article details the replacement of an obsolete Narco 50A transponder with a new Stratus ESG transponder and Stratus 2S, upgrading the aircraft's avionics.
The upgrade involved installing a more accurate 25-foot encoder and a new external GPS antenna, which now feeds satellite information to the Stratus 2S.
The installation process included careful removal of old equipment, mounting new components, and drilling/sealing a new hole in the fuselage for the GPS antenna, ensuring proper orientation and leak-free operation.

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.
