I'm waiting on some custom coax cables to arrive from China and my VZW 8800L is arriving today. Basically I'll have two hotspots that I mentioned above. I also have two roof mount antennas that I can use if I deploy my Wilson direct connect booster. The newest antenna is of the 2x2 MIMO flavor and it's omnidirectional. The brand is a Mikrotik mANT50. It really helps to have all options available in your toolbox because eventually we'll all end up in a cellular data hole and that's when an amplifier saves the day, especially when the signal is really weak. LTE in the advanced flavor takes advantage of MIMO which increases speed. If your modem uses a more advanced chip (for example Cat 16/18 capable) it'll really slow down your speed to constantly stay connected to a booster or even an external antenna in certain cases. If you have all of the options available you can greatly improve your signal enhancement when it's needed.
I think you have a really nice setup and the only thing I'd add is a MIMO antenna if your modem is capable. You also have the only intelligent booster currently on the market so I'm interested in how it'll perform for you. Once I have the new equipment I'll snap some shots for you but my booster isn't anything to write home about compared to yours.
Edit: I mixed your booster up with the CelFi model which is intelligent. Your model I believe has the antenna that has boosting built into it. Low bands are boosted within the antenna electronics vs high bands which are boosted within the amp. Sorry about that!
