Here's a translation for the first few stations in the report:
W42DG Channel 42 = WJAC NBC
WHVL Channel 27 = WHVL MYTV
WHVL Channel 29 = WHVL MYTV
W36BE Channel = WNEP ABC
The Marathon antenna is not exactly the best choice.
You don't have any VHF antennas. I'd probably start with a small UHF antenna and aim it at the direction of the channel you want.
