In addition to a large high gain antenna system, you need a tower.

Please post a couple more TV Fool reports, one at 50 feet and the other based on 100 feet.

Thanks.

It looks as if you'll need to use a tower greater than 50' tall. The 100' report is the first to suggest you could hope to see WLEX. Would you accept WNKY as an alternate NBC affiliate? I'm certain that you'll need to mount the antenna(s) above tree top level.

Reception of WBKO calls for the Antennacraft Y10713 and Antennas Direct PA-18 preamp.

The rest of the signals call for a high gain UHF antenna. They are scattered around the compass, so you'll be faced with the decision to use a rotator or multiple UHF antennas. Both choices have pros & cons.

How many TVs do you expect to connect?
