The Tv/s Must Channel Scan for the broadcast tv Channels sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for the cable tv channels.

The best reception will happen when the antenna has elbow room.
Tv antennas receive the best when there is nothing in the way to reduce or block reception.
Trees and tree leaves do a good job of reducing or blocking reception , other buildings do a good job of reducing or blocking reception.
Hills and mountains do a good job of reducing or blocking reception.
Your tvfool radar plot report shows that most of the Tv stations/channels are LOS = Line Of Sight.
Actual Line of sight , is the best type and kind of reception.
