  • 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.

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.
