Going for the USA Digital Broadcast Tv stations/channels.
The ones that are most likely to be received reliably are.
WNPI-DT REAL UHF Channel 23 , PBS.
WCFE-DT REAL UHF Channel 38 , PBS.
WNYF-CD REAL UHF Channel 18 , FOX and digital sub channel CBS is WWNY-TV.
So no requirement to receive WWNY-TV REAL VHF high band channel 7 CBS.
The rest of the USA Digital Broadcast TV stations/channels on down the channel list will Most Likely Not Be Received Reliably.
-----------
At 30 to 45 feet antenna height above ground install a Antennas Direct DB8e UHF antenna.
As a starting antenna aim direction , aim the DB8e antenna , both 4 bay bowtie panels at about , 123 degree magnetic compass direction.
Then aim 1 of the 4 bay bowtie panels at about 153 degree magnetic compass direction.
This for reception of USA Digital Broadcast Tv stations/channels.
Here is how to aim antennas ,

Use a Real and Actual magnetic compass to aim antenna.
The Canada Digital Broadcast Tv stations/channels are strong signal strength and will most likely be received by the DB8e antenna even though the DB8e is not aimed at them.
So only one antenna required to receive the USA and Canada Digital Broadcast Tv stations/channels.
