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 AT-150 combines a solid state design with high power output. The AT-150 may be used up to 30,000 feet, and its 250 watts of transmission power provide a range of 200 miles (via line of sight).

Some of our AT-150s, like the one pictured here, have a refurbished face plate and look very clean. These are used avionics that don't look used up!

The AT-150 features:

• Remote IDENT push-button capability for greater convenience
• Large combined IDENT push-button / interrogation reply light for better visibility
• 4096 discrete codes
• Mode C compatibility
• TSO'd

You may also be interested in an Encoder to use with this AT-150. When installed with an Encoder, the AT-150 will report both your position and altitude to ATC (Mode C).
