yeah that antenna would probably get you a lot of stations but as Mr You says there are better options .. the thing is you have about 7 decent power stations and a bunch that kinda fade off.. for good reception you need 30 or above and that antenna has an amp so it will amp up about 20db but any channel under Real 14 it just wont see.. I mean it might .. maybe.. ....... probably not..

something like that will probably do you but if you are serving more than 2 tvs you will need a distribution amplifier to boost the signal .. you didn't say how many you have so I would suggest this 4 port one

it may even boost your signal a bit.
You have pretty good signals. Honestly I would go to Home Depot and pickup a Winegard FreeVision and hook it up (easily returnable). This will help you determine if you really need to spend money on a dual direction UHF antenna setup.
You may also want a distribution amplifier.
See this post for more information on connecting an antenna using existing unused coax cables and sharing a single indoor/outdoor/attic antenna between multiple TVs/DVRs. The same applies to satellite coax cable runs or sharing an antenna in another room. Only difference is where you're mounting/connecting your antenna. This is something you can do yourself if the cables are within easy reach, but you can also hire a satellite installer who is willing to install antennas.
EDIT:
I would also like to try getting stations at 20 and 31 and 292 degrees.
Not sure which stations you're referring to but I wouldn't bother with anything outside the green stations.
You might try repositioning the antenna. Use your TV's signal indicator to see if there is any improvement.
Are you using any passive splitters? If so then they could be degrading the signal enough to affect reception. Try connecting the antenna directly to a TV using a coax coupler/connector to confirm this. See this distribution amplifier to resolve it or consider a preamp (Winegard LNA-200 or RCATVPRAMP1R) if you have multiple splitters (ideally you only have one).
You could pickup a Winegard FreeVision at Home Depot and give that a test. Easy to return. The Xtreme Signal HDB91x isn't going to have the best VHF performance and is overkill for your UHF stations. I suggest checking out a Winegard HD7694P if the FreeVision isn't much improvement.
This is the one that was recommended to me. I have been to lazy to buy and put one in yet. We are getting by just fine with one t.v. and our tablets for alternate viewing options.

If it were me I would probably go for a Winegard HD7694P in the attic/outdoors pointing North-East combined with a distribution amplifier (powered splitter) or preamp (Winegard LNA-200 or RCATVPRAMP1R) if you have more than a couple splitter outlets.
You can hire satellite dish installers to install antennas. If you have a chimney then mount a mast to it using chimney straps.
My ideal setup...
I would distribute an OTA antenna over all the TV coax connections in case you have a guest over and you just want to give them the remote and let them channel flip without having to explain anything. This would also be useful if your DVR is busy with no tuner available for streaming a channel live or if the TV doesn't have a settop to access the networked DVR or internet.
I would then have a 4-tuner TabloTV connected to the antenna and networked via ethernet distributing video to tablets, settops, etc., ideally via ethernet when possible: use WiFi for portable devices, use ethernet for stationary devices.
First thing I would do is since the US Stations are weaker than the Canadian stations I would point the antenna at the US Stations... just go do that now and see how you fair.
That 1by1 antenna you are looking at is not as good as the one you have right now
In the near future there will be a movement of tv stations across north america I can't tell you how soon but those stations above 36 Real on your tv fool will move lower... right now you only have a couple VHF under 13 stations but that could change. you have about 24 months or less for this to happen so investing tons of money right now is not the best idea.
Since your TV has a better tuner its getting the stations better so you can tell the difference between good and bad results is not that much.. maybe 10db or less
while the wineguard is a good amp its expensive
this amp is pretty basic.. i think the specs on it are not correct
says 50db of noise .. thats just impossible but anyway its $18

if repointing your antenna directly at 170° magnetic with your cellphone with a compass app does not give you the improvement you need then try that cheap amp and it should do ok for you
Any Yagi Style antenna is very directional .. Yagi is where the antenna lays horizontal and there are smaller elements in the front and larger ones in the back.. you can normally get about 30 compass degrees max of reception .... you are at 170 to 216 so you are outside that boundary .. your flat antenna has a wider area of reception but its only good for stations over Real 13 .. it might pick up stations below that but no guaranty.
So ... if your signal is ok for your tv.. not ok for the dust.. you just need a little boost.
Normally I would suggest a RCA with about 20db of gain
as you can see Amazon Warehouse USA has them for $18
if you can get that with free shipping for that price ... get it

Also watch your use of splitters.. never use one with more ports than you need or don't use them at all if you can get away with it.. maybe use a distribution amp that will compensate instead of a splitter.
and actually if you are using a splitter this distribution amp might be enough boost without a preamp to get you where you need to be.. its 8db boost per port
