I was going to use this for my Sonex Xenos electric motor glider, but I just realized that motor gliders do not need ELT’s. I just tested it using the set up shown in the photo…using Yaesu receiver set to 121.5MHz. It works great.


This ACK Technologies E-04 406MHz / 121.5MHZ ELT is a reliable and efficient device compatible with Avionics. It comes with:


- ELT

- Working battery, state of charge unknown

- Audible warning module

- Remote switch / indicator. Works with telephone RJ9 cable (not included)

- Antenna

- a 60-day warranty


This is a great choice for those in need of a high-quality ELT. The brand ACK Technologies is known for its exceptional performance and this device is no exception. No coax cable is included…only items shown in the photos.


The manufacturer part number E-04 ensures that you are getting the correct model for your needs. This item falls under the eBay Motors category and is perfect for those looking for aviation parts and accessories. It is important to note that this item has been previously owned but works perfectly.
