Would you rather have the rotor or mount multiple antennas? You can point an antenna at each market that seems worthwhile and combine them using separate stand-alone tuners and a HTPC to manage the streams. That will allow you to record separately from each tuner for later playback, or live streaming from any source.
No personal experience with the Lava, but you can search old posts and get a lot of opinions -
