The ARTEX ELT 345 transmits on 406 MHz and 121.5 MHz frequencies and can provide position accuracy with an optional GPS input thanks to the built-in GPS navigational interface. GPS data is embedded from the first emergency transmission and provides Search and Rescue personnel with the aircraft location, within 100 meters, in less than a minute.
This unit can be activated manually with (remote switch or ELT switch) or automatically (the G-switch detects a 2.3G or greater impact). Once activated, the ELT 345 transmits a 406 MHz signal with the beacon's unique registration information and embedded GPS coordinates to the closest search and rescue agency via the Cospas-Sarsat satellite system. The beacon also transmits a 121.5 MHz homing signal to assist search and rescue to pinpoint the aircraft's GPS location.
The ELT 345 provides a quick-and-easy retrofit opportunity with flexible installation options (standard or slim style two-wire remote switch). The ELT utilizes the same RF output using only one coax cable to transmit both 406 MHz and 121.5 MHz signals through either a 15- or 23-inch whip antenna. The ELT's built-in navigational interface does not require aircraft power to operate—which results in lower installation costs—and the stainless steel mounting bracket supplied with the unit has a multiple hole mounting pattern to accommodate legacy footprints.
