Key Takeaways:

  • The author upgraded an obsolete and failing Narco 50A transponder to a modern Stratus ESG transponder and Stratus 2S.
  • The installation involved removing old equipment, installing a new rack, a higher-accuracy encoder (25 ft.), and routing new antenna cables.
  • A new GPS antenna was carefully drilled, positioned, and sealed on the aircraft fuselage to provide enhanced satellite information to the Stratus 2S.
  • This modernization improved the aircraft's transponder capabilities, altitude reporting accuracy, and the Stratus 2S's GPS functionality.

Antenna cables

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.
