The ELT 1000 is an excellent, cost-effective option for upgrading standard 121.5 MHz transmitters, which are no longer monitored by the Cospas-Sarsat System. The ELT 1000 is a single-output ELT that transmits on both 406 MHz and 121.5 MHz using the same RF output and one coax cable. The 406 signal alone produces an accurate position within 1.86 miles, and when paired with the aircraft’s navigation system via the built-in GPS interface, the ELT’s accuracy is further improved to about 110 yards. The GPS interface does not require aircraft power to operate; the remote switch only requires two wires, which reduces installation costs and labor. *9600 standard baud rate unless otherwise requested.The ELT 1000 Base Pack (EDMO# 8204) includes the 406 MHz ELT 1000, 110-338 rod antenna, 8304 remote switch, 6-year lithium battery (LiMnO2), and installation hardware with audio buzzer and connectors.
