The Canada Tv stations Are Very Strong Signal Strength , do not use a preamplifier , the preamplifier will over load and be the cause of bad reception or no reception of some channels.
The USA PBS Tv station will also be received.
I recommend the Antennas Direct DB4e with - No preamplifier - aimed at about 140 degree magnetic compass direction , here is how to aim antennas ,

For 1 Tv connected use No splitter.
For 2 Tvs connected use a common simple 2 way splitter.
For 3 Tv's connected use a common simple 3 way splitter.

As always trees and tree leaves do a real fine job of reducing or blocking Tv reception and so buildings and other obstructions including your own building.
It is best 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 building.
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.

Install the DB4e antenna , scan for channels.
Do a Double Rescan , Digital Tuners can develop ' digital glitches ' that are not cleared out with a simple channel scan.

WCAX-DT REAL UHF Digital channel 22 , virtual number (3.1) CBS.
WPTZ-DT REAL UHF Digital channel 14 , virtual number (5.1) NBC.
Are both Very Weak Tv stations with Co-Channel Interference and Adjacent Channel interference.
After the scan for Digital Broadcast Tv Channels you will find out if 1 Tv connected can lock on to the signals.
