MOST of the mounted ELT's will still function, though at a reduced TX range
without the antenna should it be severed in a crash...

Personal ELT's and EPIRB units require you to activate them manually....if
you're still, after you crash.... able to!

1) The installed ELT has more power and a better antenna.

Unless the coax is severed or the fragile battery box is broken.

2) The installed ELT has a button on the panel to turn it on
quickly before landing. I'll bet hitting a button mounted
at a fixed location can be done faster than finding a button
on a portable.
