I decided on a 406/121.5 ELT with integrated GPS, antenna and battery by Kannad. It’s the Kannad Integra AF. It comes with a remote panel switch and it will source the ships GPS location as a backup.
Since 121.5 is no longer officially monitored, it’s a good idea to have a 406 ELT. The 406 will send my GPS location via satellite with it’s specific identifier. They’ll be able to look up my specific aircraft and pilot details along with phone numbers and names of people I specify. Then when search and rescue gets there, they’ll be able to home in on the 121.5 signal.
Several people have mounted the external antenna inside the fuselage. I decided to mount the antenna instead in accordance with the installation manual with the antenna external to the fuselage. Since the part of the fuselage will be fabric, I’ll need to build a ground plane with copper tape. Look for a future post on that.
