"- By old FCC rules, FRS radios are limited to 1/2 watt of transmit power."
That's true, but under the *new* rules, didn't they raise that to two watts?
The "unity gain" aka "no gain" Browning antenna sets about as low a goal as you can find. But the TypeN connector they use *is* actually better than the common SO-239/PL-259 "UHF" connectors. It has less loss at these frequencies, creates less of an impedance bump [more loss] in the cable, AND it has a built-in o-ring to make it fairly water resistant, the bane of UHF connectors used outdoors.
If the goal is really maximizing performance, I'd find a better antenna (I think Laird and Wilson both make 5dbi gain versions for this, among others) that still uses the TypeN connector. And either at the antenna, or still on the outside of the house, connect the cable to a PolyPhaser (brand) lightning arrestor. From that you run one more coax into the building, and one proper grounding cable into the ground. PolyPhaser are what commercial broadcasters use for lightning protection on their towers, the stuff isn't cheap but neither is a new house.
"Range" is a two-way thing. If you are trying to use the base station to work with handhelds? There is only so far that the signal from the handheld can go, and then you won't hear them, regardless of the base station. Your best bet is when the handhelds and the base have equal abilities, or at least "sufficient" ones to make sure it works both ways.
With a five watt (maximum handheld) ham radio, even on the VHF band (which travels better), and a repeater that is literally pushing over 50 watts 100 stories up in the air, with a clear line of sight? A range of twenty miles would be pushing things.
Same handheld can reach the ISS orbiting over a hundred miles dead overhead in the sky though. Physics is tricky that way.(G)
