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.

My two new antenna cables. One of the cables goes to the whip antenna located on the belly of my airplane, and the other one goes to my new GPS antenna. The cables were routed down the right side of the cabin, under the rear seat, and through the baggage area to the rear of the fuselage using existing cable routing.
