Your location has many Strong Tv stations/channels to receive in All Three Tv Bands of , VHF low band channels 2 thru 6 , VHF high band channels 7 thru 13 , UHF band channels 14 thru 51.
I recommend a Tv antenna that designed to receives All 3 Tv Bands.
A Winegard HD7082P antenna is designed to receives All 3 Tv Bands , the price at
http://www.solidsignal.com is $70.99.
The HD7696P antenna is not designed to receive all 3 Tv bands , the HD7696P antenna is designed to receive , 2 Tv bands , VHF high band 7 thru 13 and UHF band 14 thru 51. The price of the HD7696P antenna at
http://www.solidsignal.com is $77.99.
Install the HD7082P antenna in the attic aimed at about , 170 degree magnetic compass direction.
Here is how to aim antennas ,

For 1 Tv connected use no splitter , no antenna amplifier.
For 2 Tv's connected use a common simple 2 way splitter , no antenna amplifier.
For 3 Tv's connected use a common simple 3 way splitter , no antenna amplifier.
Install the antenna up as high as possible in the attic , keep it away from the air conditioning/heating duct work and etc..and not in the way of reception to the south.
As always trees and tree leaves do a real fine job of reducing or blocking reception and so do buildings and other obstructions.
It is best to locate the antenna at a location that has the least amount to no amount of obstructions of any type or kind in the direction of reception.
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 cable tv channels.
