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. The ELT utilizes the same RF output using only one coax cable to transmit both 406 MHz and 121.5 MHz signals through the compact 15-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.

Yes, for Canada order the international version. The ELT must be programmed to the country that the aircraft is registered to.
Most antennas require a ground plane size of approximately 24" by 24". While the rule of thumb is to Provide a minimum of 1/4 wavelength of the operation frequency, larger is better and ground plane symmetry is critical.
This unit requires a GPS signal, it does not have its own.
The ELT does not require a GPS input to function, however it is highly recommended.
You would get the US version since the aircraft has US registration.
