Due to the 243MHz cessation, most of them are discontinued.

The RF connectors are 50 ohm BNC on both units so this cable can be left unchanged.
If an alarm is detected, they initially phone some pre-registered number(s) to check for a business plan for indian restaurant pdf false alarm and only then is the search/rescue process activated.Kannad Wiring, the existing Socata TB GT ELT wire (3 cores plus shield) is simply re-used as follows: The three wires could of course have been used in any order for the three Kannad signals.Self Test, g-Switch Enabled, 406 MHz Power, Antenna/Coax Connection, Low Battery.The RF cable is fine at its current length.Avionics section of Ebay, though one doesn't get a lot for.
Battery 6-year Lithium (LiMnO2, solid cathode Replacement Battery Part.
Anyway, it isn't a good idea because the external insulation could be abraded to the airframe somewhere.
The pricing is comparable too, even after allowing for Kannad pricing the switch and antenna separately whereas Artex seem to sell a whole kit.
Testing The installed ELT is tested for its 121.50 emission (tune the radio to 121.50 and follow the instructions in the manual) but one does not test the 406MHz part.
Update 3/2016 : The FAA Chief Counsel has issued this ruling on ELT installation which suggests that the installation is not a Major Alteration.
This article describes the installation of the above ELT in a Socata TB20GT aircraft.The instrument panel switches differ in appearance but their overall front panel dimensions, mounting hole sizes, and the four mounting screw hole locations are identical which saves hacking the instrument panel.The most "obvious" replacement for the Artex ELT-200 is the.An important requirement is to use the existing instrument panel hole, and the existing wiring.Kannad seem to offer some kind of online 406MHz test facility and a voucher is included in the package; I need to check this out.Socata wiring is a 3-core plus shield cable and one solution would be to use the shield as the 4th conductor but I have not managed to get Artex to supply information on what the signals do so it was not possible to work out.Artex ME-406 ( installation manual ) which claims to fit onto the same mounting points.Artex 110-4 and these installations reportedly have enough wires for the ME-406.Activation, automatic.5 feet per second (2.3 G) Primary G-Switch or Manual Activation.Plus some additional holes.
I suspect it would not accept a G-number for example.
The larger tri-band (121.5243406) ELTs which were popular a few years ago are not worth installing because 243MHz monitoring ceased in 2009, and they need an adaptor bracket to be made which some avionics installers like to turn into a major certification project.
The two antennae are very similar.
