So, I could set it for "bridge" operation, toss it on the deck with the
antenna high to extend my range to -- how far? I seem to be getting
about a half mile, line of sight, at the marina with the internal
antenna.

Yes. Using a 9 db omni-directional antenna 20 ft off the water, I
have maintained solid connections at 3 to 5 miles. That assumes an
outdoor AP on shore with a decent antenna also. Indoor APs usually
top out at 1/2 mile or less depending on the situation but sometimes
more. I can access my own indoor AP from about 1,000 ft, going
through a wall, glass doors and pool screening.

The POE injector inserts power into the ethernet cable to operate the
bridge. It consists of a small wall wart transformer going to an
even smaller box with ethernet in/out jacks.
