I'm not a developer, and this is my first post here, so please go easy on me. How about an app to assist in aiming an antenna for the best DTV reception? The FCC provides a (Google) map of broadcast antenna locations. The map and database are searchable by address (GPS?). An app combining that info with a compass overlay (for example), would have been very useful when I was on my roof yesterday. Including a satellite dish aiming feature would make it even better!
