As the RT-459A has gotten older, it has not aged gracefully. We no longer recommend the RT-459A for a new Transponder installation.

Unless you are replacing another RT-359A or RT-459A and don't want to perform a new installation, we recommend that you consider the Garmin GTX-327 (Mode C), GTX-330 (Mode S), GTX-335 (ADS-B Out), or GTX-345 (ADS-B In/Out) instead.

The ARC (Cessna) 400 Series RT-459A Transponder is a direct replacement for the common RT-359A. The RT-459A takes the basic RT-359A chassis and adds more power and convenience. The additional power allows this transponder to be used to 30,000 feet. The tuning levers are a bit unusual, but they work very quickly once you get accustomed to them.

Some of our RT-459A transponders, like the one shown here, have ARC's tan faceplate. Please check availability, as we may have units with black faceplates as well.

If you need a black faceplate to match the rest of your radio stack, and we are currently sold out of black, we can change a tan faceplate to a refurbished black one for $75 extra. Our refurbished faceplates look great.

The RT-459A is compatible with encoders (either an encoding altimeter or a blind encoder).

The RT-459A features:

• 200 watts transmission power
• Mode C compatibility
• TSO'd to 30,000 feet
• Reply light dimmer
• Self test function
• Provision for remote ident switch

You may also be interested in an Encoder to use with this RT-459A. When installed with an Encoder, the RT-459A will report both your position and altitude to ATC (Mode C).
