For the reception of the groups of Tv stations to the north east and south west.
The Digital Tv stations in the Green reception zone should be received.
If there are reception issues that can not be corrected buy antenna aim or location in the attic , when the weather is warmer move the CS2V Complete to above the second story roof.
The signal strengths are strong at your location.
A preamplifier 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.

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 antenna at a location that has the least amount to no amount of obstructions of any type or kind including your own house.
The Tv's Must Channel Scan for The Digital Broadcast Tv 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 the the receiving antenna.
Some Digital Tv's automatic channel scan for cable Tv channels.
Go into the Tv setup menu and select , 'Air Channels' / 'Antenna Channels.
DO NOT channel scan for cable tv channels.
