Query about using an external antenna for 4G reception

Currently, my only form of broadband is via mobile broadband with THREE (using Netgear AC762S), and Vodafone (using R212)... and the reception is alright but could be better.

I plan on getting an unlocked Huawei B593s-22 Router for the both of them, to which would be hooked by to powerlines to network the entire house, and having an external antenna installed on the roof to improve the reception using 2 of these (LINK).

They're directional. My question is this:

I plan on having it face THREE's mast, while Vodafone's mast is roughly 90° away from that... How much would this effect the reception with Vodafone, and for curiosity's sake what would it be like in the opposite direction?
 
The answer is actually in your link. Good antenna manufactures always include a chart that shows the signal graph.

You can see like most direction antenna they get very little reception at 90 degrees. These antenna pretty much do not get a lot of signal past 45 degrees off the center. Generally this is a very good thing since it cuts the interference from other signals.

This graph is very common for a yaggi. You will note it get quite a bit of signal from the back end of the antenna. If this is a issue parabolic tend to have much better rejection of signals from the back.
