^ A similar approach to a base station is a mobile setup. The same power radio into a good antenna will get you much more range than a handheld. Not as much as a base station with a better antenna, but still an impressive improvement. Here is the Florida suburbs (flat with trees) my HT is maybe two miles, but my cheap 25W mobile into a small mag mount antenna is at least ten miles.
The added benefit is that it's mobile. Assuming there are not massive trees on the roads post hurricane, I can drive the 4x4 to high ground for good comms. Can't do that with a base station. You can always move it inside to use as a base unit.
