GTX328 with AK350

Garmin GTX328 Mode S transponder with AK350 altitude encoder

Removed in serviceable condition during equipment upgrade.

The GTX328 is complete with mounting rack and I have updated the unit software to the latest version, v8.04.

I have made a brand new wiring harness for the system, and bench tested everything prior to this sale. It provides a very straightforward installation - just two wires (plus the antenna).

I have also included an Ameriking AK350 altitude encoder, again this unit is in removed serviceable condition and wired into the transponder.



Collection is preferred, I am based in the Brighton area of East Sussex. Shipping is available via a tracked and insured service.

I can provide an antenna and cable at extra cost if required.
