Antenna suggestions Johnstown OH

[briteflite]

Would appreciate external antenna suggestions for our location. Mostly interested in the Columbus OH stations to the southwest (channels 21 14 48 36) and channel 38 to the northwest.

Here's the radar plot:

I suggest a Winegard HD7694P antenna pointed at about 250 degree magnetic compass. How many Tv's will be connected??
