Correction; I found the game listed in the Comcast channel guide for Friday and Saturday for channel 202. Those of you who have Comcast in the SW suburbs should be all set...
As far as the antenna goes, I just hooked it up to the TV, switched the mode from Cable to Antenna, and then did a search for available channels. One of the channels was TPT-MN which just happened to show up as channel 2.2 on my TV.
Try hooking up just your rabbit ears and seeing what channels you can pick up...
