This is what I was looking for. Thank you!

Just brainstorming here.... if I had a wire connected from transmitter to
receiver undeployed antenna... it would do the same as a deployed antenna?

Maybe. Depends on the details of the circuit design. You're almost
certainly going to end up overdriving the receiver, possibly far enough to
damage it--remember that it's designed for less signal strength than it's
going to be getting down the cable. Then there's the matter of matching
impedances. Then there are likely other factors that I haven't
considered--I know enough electronics to be dangerous, but not enough to be
good at it.
