Emergency Personal Locator Beacon Teardown

 

AvE got his hands on an Emergency Personal Locator Beacon. This is one of the few things made in Canada! Looks like no expense was spared in the build. The lithium batteries are still operational even though they were dated to expire 16 years ago. I have never seen the  tape measure like antenna. Without making an electrical connection is it doing anything? I was expecting to see a gold plated portion that lined up with some wiper arm.
