Product Description

As the AT-50A has gotten older, it has not aged gracefully. We no longer recommend the AT-50A for a new Transponder installation.

The Narco AT-50, AT-50A, and AT-150 are all directly interchangeable.  If you have one of these Transponders, and want to minimize the installation effort, we strongly recommend the AT-150 over the other Narco choices.  While still an old Transponder, it offers better reliability than either the AT-50 or AT-50A.

The Narco AT-50A is a very common transponder, and is an upgrade of the original AT-50. The AT-50A offers basic transponder functionality at a reduced cost (compared to King and Collins). The AT-50A features:

  • 250 watts of transmission power
  • 4096 discrete codes
  • Mode C compatibility
  • TSO'd

You may also be interested in an Encoder to use with this AT-50A. When installed with an Encoder, the AT-50A will report both your position and altitude to ATC (Mode C).
