Is the ELT ground tied to the plane's ground? :-)

It is in my Piper Arrow. It uses the airplane's ground both for the
antenna groundplane, and also as a return path for the remote switch.

In fact, if you unhook the fuselage antenna from the ELT then the remote
switch no longer works. [Questionable design, but that's the way it came
from Piper.]
