The Artex 455-6604 Me406 HM a single output ELT, utilizing the same RF output and only one coax cable to transmit 121.5 and 406 MHz emergency signals to the Cospas/Sarsat satellites. The ELT automatically activates during a crash and transmits a continuous swept tone on 121.5 MHz During activation, the 406 MHz transmitter sends an encoded 5 watt signal every 50 seconds for 440 milliseconds to alert Search and Rescue.
The mounting hardware for the ME406 Series is compatible with all previous models of Artex 406 MHz ELT products, as well as the ELT-200 Series, ACK, Pointer Model 3000 and Narco ELTs. Current owners of Artex 2-frequency TSO C91a ELTs can re-use the remote switch in the cockpit, as well as the wiring harness from the cockpit to the ELT. This greatly reduces installation costs.
