I recommend go for the groups of Digital Tv stations/channels to the , west north west and south east.
Install a Clear Stream 4 UHF antenna , with the Reflector Screens Removed , so the CS4 antenna UHF Tv channels 14 thru 51 Reception Loops , will receive both directions , at the front of the CS4 antenna and the back of the CS4 antenna.
Aim either side , front or back , at about 125 degree magnetic compass direction.
Here is how to aim antennas ,

Also contact ,
http://www.antennasdirect.com , and buy the VHF channels 7 thru 13 -> Metal Reception Rods<-> Upgrade Kit.
And install the , VHF Reception Rods Upgrade Kit on to the CS4 antenna.
_______________
The Digital Broadcast Tv stations/channels in the , Digital Pending Applications Included - Green and Yellow reception zones radar plot and channel list are , moderate to strong signal strength at your reception location.
_____________
A antenna system amplifier will most likely not be required.
_____________
For 1 Tv connected use No splitter.
For 2 Tv's connected use a simple common 2 way splitter.
_____________
The trees and tree leaves will most likely cause some signal reception problems of the Digital Broadcast Tv stations to the south east , the extent of the reception situations of the Tv stations to the south east will only be known when the antenna is Up In The Air receiving the Tv transmissions.
Clearing/having the antenna higher then the trees will lessen the reception problems/situations.

You have not said what antenna mounting you are using for the antenna.
Here are some antenna mounts that will get the antenna Up In The Air.

As always , trees and and tree leaves , plants and plant leaves , do a good job of , absorbing , multi-path/reflecting , blocking , OTA=Over The Air , Digital Broadcast Tv Reception and so do buildings and other obstructions including your own roof and house.
It is best to install the antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception.
The Tv/s Must Channel Scan for the 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'.
