Take to the skies with confidence with the ELT 345. This emergency locator transmitter is equipped via NAV interface, so if you run into an emergency, search and rescue teams will be given your aircraft location in less than a minute, within 100 meters. In addition to providing position accuracy, the ELT 345 transmits on 406 MHz and 121.5 MHz frequencies. Like all our products, this ELT is built to surpass industry standards, and ensure you'll get the help you need. Be Prepared for the Unpredictable: - Manual and automatic activation - Two-wire remote switch - Flexible installation - Stainless steel mounting bracket - Built-in navigational interface

When an emergency happens, rely on the same brand that leading aircraft manufacturers trust for first-class quality, superior technology, and outstanding customer service. The new ARTEX ELT 345 is built to the industry’s most stringent quality management standards to ensure the ELT works the first time, every time. The ARTEX ELT 345 transmits on 406 MHz and 121.5 MHz frequencies while providing positon accuracy thanks to the built-in GPS navigational interface. GPS data is embedded within the first emergency transmission and provides Search and Rescue personnel with the aircraft location, within 100 meters, in less than a minute. The ELT 345 boasts an industry low price for an ELT providing the same quality and performance on which the ARTEX brand was built.

FAA TSO C126b approved.


  • The ARTEX ELT 345 can be activated manually (via cockpit remote switch or ELT switch) or automatically (the G-Switch senses a 2.3G or greater impact), and alerts the closest Search and Rescue agency of your emergency. The 406 MHz signal, containing your GPS coordinates, is transmitted to the Cospas-Sarsat satellites and relayed to the Mission Control Center where it is immediately routed to the nearest Search and Rescue agency. Your beacon’s registration will tell first responders who you are and the beacon itself lets them know where you are to within 100 meters. Finally, the local 121.5 MHz homing signal assists Search and Rescue forces to identify your exact location.

How it Works

  • The ARTEX ELT 345 provides a quick-and-easy retrofit opportunity with flexible installation options such as a two-wire remote switch that does not require any aircraft power. Because it is a single output ELT, the ELT 345 utilizes the same RF output and only one coax cable to transmit both 406 MHz and 121.5 MHz signals. The built-in navigational interface does not require aircraft power to operate which greatly reduces the cost of installation. The stainless steel mounting bracket has a multiple-hole pattern configuration which makes the replacement of legacy ARTEX ELTs or old ACK, Kannad and AmeriKing ELTs quick and easy.

  • Pair the ELT 345 with ARTEX’s exclusive online satellite confirmation testing system,, and get real-time beacon testing results, from the same satellites used by Search and Rescue, to ensure your ELT system is functioning properly. There is a reason that ARTEX ELTs are the choice of more aircraft manufacturers than any other; they trust ARTEX to build the highest quality products knowing they are used to save lives.

Great inexpensive ELT with all the quality of the high end units. I replaced a very old ELT in my 1948 Navion A with the Artex ELT 345.

I love the ELT345s but I wish Artex would provide a DB connector for pins vs soldering. Users should absolutely be aware of the 50-second test period before the 406 signal goes active. One that 406 signal goes active, it could get real expensive if elicits a false alarm air search.

This is a high quality item and includes almost all the components youll need to install this ELT in your aircraft. For example, the antenna comes with its own coaxial cable and the D-sub connector comes with pins and a backshell housing. The only thing you need to supply is the tefzel wiring. One thing to be aware of with this unit is that it does not have an actual built-in GPS nav unit to give your position in case of emergency if you read the description carefully, youll see that it is ABLE to transmit a GPS signal, but that signal has to be provided by an outside source, like a panel-mount NAV GPS or a handheld unit. And you should make sure that you know what GPS you plan to use, as the signal output rate (Baud rate) needs to match with this unit. It can accept either Aviation Data format (9600 baud) or NMEA (4800 baud) and needs to be programmed into the ELT.

Easy install, unit came complete with pretty much everything needed. It tested ok. I hope I never need to find out if it works in a crash.

Had it in stock, quick shipping and great price. Meets my needs completely!

This ELT was a perfect replacement for my legacy ARTEX 121.5 in my PA-38 which had originally been relocated to the epanage from the center console by the previous owner . I had to order 12 ft of braided twisted pair milspec shielded wire to replace the existing wire in order to avoid any interference issues. The unit passed the testing and is up and running and the new whip antenna is just fine. All in all a great value!

We have installed many of these units! Very impressed with Artex and their development of this reasonably priced ELT for general aviation.

This is a replacement unit so I am in the process of installation. My impressions to date are that this is a solid product but there are a couple of things to be aware of: 1: the panel switch is significantly larger that my previous unit which means a panel modification not plug a play. 2: the unit comes with no wiring diagrams in the box you have to go to the web site an surf thru a 50 page document for the wiring diagram. 3: the antenna is atrocious there is no way I would put that on the exterior of my aircraft. Fortunately for me there is space under my Plex canopy that it will fit. 4: you need to be proficient in soldering din connectors.
