The EBC TK-1 Test Kit has been designed to allow users to perform functional testing of an EBC 406 series ELT outside of its’ mounting bracket. This test board plugs into the ELTs 15-pin connector and allows for testing of the auto-activation system as well as the electronics. It has a 50-ohm terminator that is plugged into the ELT’s antenna connector to prevent false signal transmission while testing. It is light and easy to use. It comes with a storage case and complete instructions.
