The signal strengths of the USA and Canada Tv stations/channels are Very Weak Signal Strengths.
-------------
For reception of USA , Digital Broadcast Tv Stations /Channels.
WNYF-CD , Real UHF channel 18 has , FOX and CBS.
WWNY-TV , Real VHF high band channel 7 has the same networks as WNYF , CBS and Fox.
----------
WNPI-DT , Real UHF channel 23 is the same PBS as WPBS Real UHF channel WPBS-DT Real UHF channel 41.
WWTI-DT Real UHF channel 21 is , ABC and The CW.
------------------------------
For Initial Testing of reception have only 1 Tv connected , No splitters.
It is a tough call on antennas and preamplifier recommendations.
My final choice is the same antenna and preamplifier as , GUM's , recommendation.
Aim the HD7698P antenna at about 197 degree magnetic compass direction.
Here is how to aim the antennas ,

Use a Real and Actual magnetic compass to aim antenna.
-----
As always , the starting antenna aim direction is the -->starting antenna aim direction.
The antenna aim can be adjusted for best reception.
To that end , Most Digital Tv's have a Signal Strength Meter and some Digital Tv's also have a Signal Quality Meter.

Tvfool shows.
CKWS-DT , Real VHF channel 11 , The CBC , is a little further to the South West
and might be received reliably.
If not then the antenna can be turned a little more toward the South West to improve reception.
Without losing reception of the Very Weak Signal Strengths , WWTI-DT and WPBS-DT.
