(be the first to review)

The Garmin GTX 345 is a Mode S Extended Squitter (ES) transponder, known for its ADS-B (Automatic Dependent Surveillance-Broadcast) capabilities. It’s designed to provide aircraft with compliance to the ADS-B Out mandates while also offering ADS-B In capabilities for enhanced situational awareness. Overall, the Garmin GTX 345 is a versatile transponder that not only ensures compliance with ADS-B mandates but also enhances safety and situational awareness in the cockpit through its ADS-B In capabilities.


The GTX 345R is designed to provide both ADS-B “In” and “Out” capabilities, meaning it can receive ADS-B information from other aircraft and ground stations while also transmitting its own ADS-B data. The “diversity” feature typically refers to the presence of multiple antennas for enhanced reception and transmission reliability, particularly in areas with challenging radio environments. This type of transponder is crucial for compliance with modern airspace regulations, as ADS-B (Automatic Dependent Surveillance-Broadcast) is becoming increasingly prevalent as a means of air traffic control and situational awareness. By both receiving and transmitting ADS-B data, aircraft equipped with the GTX 345R can participate in the ADS-B ecosystem, enhancing safety and efficiency in the airspace.
