It’s odd because a “communications facility” is usually a secure building.

Given the location and that it was Coast Guard, I'm guessing it's where they handle calls from ships/people in distress, which is not exactly national security. They do a helluva lot of rescues up in that region.

Now if it had been an Air Force "communications facility", that's a completely different story...

It would still be secured, because of the nature of the equipment inside. Even the radio room on a CG cutter is a secure space.
