The following is a Teleview recommendation for broadcast Tv reception.
As often happens in multipul hilly country the signal strength of the weak signal strength Tv stations does not improve with higher antenna heights.
For your reception situation , 10 feet or less antenna height looks like the best for reception.
The Digital Tv stations/channels to the east.
WQMY , REAL UHF channel 29 , MyNetwork and FOX and CW. Strong signal strength.
W20AD-D , REAL UHF channel 20 , ABC and Antenna Tv. Weak signal strength.
WBRE-DT , REAL VHF channel 11 , NBC. Weak signal strength.
WYOU-DT , REAL VHF channel 13 , CBS. Weak signal strength.
If you will like to try for the weak Tv stations that are listed above.
Install a Winegard HD7698P antenna with a Antennas Direct CPA-19 preamp , aimed at about 96 degree magnetic compass direction.

For 1 Tv connected use no splitter.
For 2 Tv's connected use a , HFS-2D , 2 way splitter.
For 3 Tv's connected use a , HFS-3D , 3 way splitter.

As always , trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions.
It is best to locate the antenna at a place that has the least amount to no amount of obstructions of any type or kind.
The Tv/s Must Channel Scan for the Digital 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 cable tv channels.
