The Artex C406N is a single output ELT that incorporates latitude/longitude information from the aircraft navigation system.

By use of an optional programming adapter, the ELT can also be programmed with the aircraft's 24-Bit address for fleet operators as well as other custom programming. All 3 emergency frequencies (121.5/243.0 and 406.028 MHz) utilize the same RF output, which requires only 1 coax cable to connect to the new series of Artex single input antennas. The ELT automatically activates during a crash and transmits the standard swept tone on 121.5 and 243.0 MHz. Every 50 seconds for 520 milliseconds (long message protocol) the 406.028 MHz transmitter turns on and transmits an encoded digital message to the Cospas/Sarsat satellite system. Also available is the Artex C406-N HM, which is equipped with a 6 axis "G" switch for helicopter installations.
