The Digital Broadcast Tv stations/channels are Strong signal strength at your location.
A Winegard HD7000R antenna will easy receive the Tv stations.
I recommend install the Winegard HD7000R antenna above the high point of the roof.
Aim the HD7000R antenna at about 235 degree magnetic compass direction.

Buy the ronard antenna mounts at solidsignal by typing the word ronard in the solidsignal search box or buy from ronard.
A Winegard DS3000 , J pole type antenna mount will also work for mounting the - light weight -HD7000R antenna above the high point of the roof.
The DS3000 , J pole type antenna mount will not work for Big heavy antennas.
As always , trees and tree leaves do a good job of , reflecting , reducing , blocking , Digital Tv reception and so do buildings and other obstructions including your own roof and house.
It is best to install the HD7000R antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception in the direction of reception including your own house.
The Tv/s Must Channel Scan for the , OTA = Over The Air , Digital Broadcast Tv stations/channels , often 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.
Some Digital tv's will automatic channel scan for cable tv channels.
DO NOT channel scan for cable tv channels.
Go into the Tv setup menu and select , 'Air Channels' / 'Antenna Channels'.
