All the channels you will like to receive are UHF channels , and are easy to receive with one UHF antenna. I suggest a Antenna Craft U4000 Uhf antenna pointed at about 110 degree magnetic compass. Here is how to point Tv antennas ,

The stations to the 'east north' WGPX 14 ION at 85 degree magnetic compass to WGHP 35 Fox 'east south' at 134 degree magnetic compass will be received. The stations WXII-DT 31 NBC and WUNL-Tv 32 PBS to the north are Very Strong Stations and will be easley received through the back side of the antenna. So one antenna will do it. The antenna needs to be roof mounted.
