EBC 406APHM – AUTOMATIC PORTABLE MILITARY HELICOPTER EMERGENCY LOCATOR TRANSMITTER

Cabin or cockpit mounted military helicopter ELT transmits on three frequencies (406.028, 121.5 & 243.0MHz). Is painted flat black, uses an external rod antenna. Meets TSO-C91a and TSO-C126.

Product Manual

The EBC 406APHM cabin mounted ELT is for rotary wing military or governmental aircraft in which night vision equipment is used but where an external antenna is desired. These ELTs are painted a non-reflective flat black to be night vision compatible. The EBC 406APHM has an external rod antenna and so it can be installed anywhere in the cabin of the aircraft provided that the pilot can reach it in case of an emergency. Because it is within reach no Remote Control Monitor is necessary. To meet the needs of ourmilitary or governmental users these ELTs transmit on three frequencies: 406.028, 121.5 and 243.0MHz.

The system comes with a transmitter, survival tape antenna, mounting bracket, a battery pack and a rod antenna with a 6 ft. cable. If the ELT is activated a built-in monitor emits a loud beeping tone and the LED flashes. The survival antenna allows the ELT to transmit a good signal when used outside the aircraft.

Intended for military or civilian governmental use it has been designed with the newest technology. The EBC 406APHM incorporates the best and proven features that characterize all of EBC’s emergency locator transmitters. These transmitters have encapsulated electronics and battery packs to provide added protection against shock, moisture and other environmental hazards.

A self-test feature is built into the EBC 406APHM. This feature allows the pilot to test for output power on both 406.028 and 121.5 MHz, the connection with the antenna, and the condition of the digital signal.

The EBC 406APHM is approved by the FAA under TSO-C91a and TSO-C126, approved by COSPAS-SARSAT and meets FCC requirements under Part 87.
