Can the same WAAS GPS receiver serve as the GPS input to an ELT which has a 'GPS Interface', using a coax signal splitter? (I'm assuming it uses coax for that connection)

Since an ELT is "never" used, can it's signal be routed thru the comm antenna, again using a splitter - rather than carrying around an extra antenna forever?

Or, have I totally misunderstood how these work?!? Thank you!
