Wireless Joint

So I face a bit of a dilema where I live. We get no reception in my home without the help of a booster. I had a basic Wilson which was not terrible but not what I wanted either. I recently upgraded to a Cel-Fi Go X and I am in the proccess of maximizing it's potential. I am 9.7 from tower with no LOS. I have my yagi 40 ft up. I am considering the flat panel that is sold by The Wireless Haven. https://thewirelesshaven.com/shop/antennas/4g-lte ... l-antenna/

Will this antenna help me any? My current antenna goes throught the tree tops the best I can tell.
