Your best reception with a indoor type antenna will be with a Terk HDTVi (not the HDTVa) indoor antenna , at/in a window that is toward the , north east.
Aim the HDTVi antenna at about 35 degree magnetic compass. Here is how to aim indoor type antennas ,

When your are ready to go for reliable and stable reception.
I recommend a Winegard HD7082P antenna above the roof , installed in such a manner that the roof or house is not blocking reception to the , north east.
(I recommend the HD7082P antenna , it has better antenna gain - reception ability - on the VHF low band channels of 2 thru 6 where your reception situation requires more reception ability)
Aim the HD7082P antenna at about 35 degree magnetic compass direction.
Here is how to aim outdoor type antennas ,

No preamplifier is required.
For 1 Tv connected use no splitter.
For 2 Tv's connected use a common simple 2 way splitter.

As always trees and tree leaves do a real fine job of reducing or blocking Tv transmissions and so do buildings and other obstructions including your own house.
It is best to install a antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own house.
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.
