Garmin's GTX 320A Transponder web site
The panel-mounted GTX 320A is a low cost, dependable,
pilot-friendly Mode C transponder. For even more options, the companion
GTX 327 Mode C transponder comes with a DSTN LCD display and additional
features that reduce pilot workload.
Enjoy Solid State Design
Like all Garmin transponders, the IFR-certified GTX
320A features a solid state design, and with no warm up time, lower
power consumption and much lower heat emissions, you’ll enjoy a longer
service life. Transmit codes are dialed in using traditional knobs, and
the 320A operates on 14- or 28-volt power.
Upgrade Easily
GTX 320A’s compact, lightweight design makes it easy
to install in the tightest spaces. The 320A fits into existing
installations of select Narco and King transponders using optional
adapters for simple, cost-effective upgrading.
