I just did a search, and it looks like most of Walton County still doesn't have local networks. (It looks like if you're Villa Tasso/Choctaw Beach or otherwise have a Niceville zip code, they might let you have the Mobile-Pensacola locals.)
We'll lose signal for maybe 5 minutes when we get one of those 3-4 inches an hour cloudbursts, but a good normal thunderstorm doesn't cause signal disruption. And the dishes hold up well in windy conditions. We never lost signal when Ivan was making landfall, (freakishly, we were part of the 2% of Okaloosa County that never lost power) and it was actually kind of weird watching the ride-out crew on WEAR talking about how their tv and radio rebroadcast towers were all down, but that they'd had reports that Crestview cable viewers could still watch, and we almost called up the station to say the the Niceville along Hwy 20 (ie. power on) folks who had satellite could still see them too.
