Hi - Signal is pretty strong for the stations around 223 magnetic. I'd rerun the report with an exact street address - use the "Start Maps" on the front page, and adjust to your exact location. Then select the button "make radar plot." Your address will not be included in the final plot.
Had you planned to mount the antenna on the roof? Getting above any close-in trees will be worthwhile. See "Trees and UHF" here -
http://www.hdtvprimer.com/antennas/siting.html You should be able to get the Baton Rouge stations down the list to KBPN or so with a modest rooftop antenna like the ANT751

Of course, you can go bigger if you want to. Possible you could pick up some New Orleans stations with more antenna and height.
