C406-2 Series
(DAI Part# 455-5000)
Single output 406 MHz emergency locator transmitter
(Type AF ELT) Cospas/Sarsat approved
FAA TSO C126 and JTSO-2C126 approved

The Artex C406-2 transmits on all 3 emergency frequencies (121.5/243.0 and 406 MHz). 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 406.025 MHz transmitter turns on and transmits an encoded digital message to the Cospas/Sarsat satellite system.

The ELT can be programmed with the aircraft's 24-bit address as well as latitude/longitude information from the aircraft navigation system when used with the Artex ELT/NAV Interface (P/N 453-6500). Also available is the Artex C406-2HM, which is equipped with a 6 axis "G" switch for helicopter installations.

The mounting hardware for the C406-2 series is compatible with all previous versions of Artex 406 MHz ELT's.
