The Local Canada Digital Broadcast Tv Stations/Channels are Very Strong Signal Strength , are LOS=Line Of Sight and Less then 3 miles away.
The amplifier in the HDTVa antenna will most likely over load from the strong local Canada transmitters.
The HDTVa can operate in a amplified mode and a non amplified mode.
The HDTVa Must remain plug in to electric power at all times.
A switch on the unit can turn the amplifier on or off.
But for the amplifiers on off amplifier function to work the Power supply Must Remain Pluged in to electric power.
And for the HDTVa to work to receive Tv transmissions the HDTVa -->Must be Pluged into Electric Power.
-------------
For better reception put the HDTVa in/at a South facing window.
Aim the HDTVa at about 160 degree magnetic compass direction.
Here is how to aim indoor and outdoor antennas.

Use a Real and Actual magnetic compass to aim antenna.
If a coax is running through the living space to get from the HDTVa antenna to the Tv , then so be it , because Reliable Reception is more important them objections to coax running through the living space.
--------------
The Tv Must Channel Scan for the , OTA=Over The Air , ATSC-Digital Brroadcast Tv Stations/Channels , often named the ~ Antenna Channs ~ ATSC Channels ~ DTV Channels ~ Air Channels ~ in the Tv Setup Menu Because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
Some Digital Tuners will Automatic channel scan for cable Tv channels.
DO NOT channel scan for cable Tv channels.
Go into the Tv Setup Memu and select ~ Antenna Channels ~ ATSC Channels ~ DTV Channels ~ Air Channels~.
Channel scan for ATSC-Digital Broadcast Tv Channels.
