Wayne - I have the WeBoost by Wilson Engineering that Eric at Techno sells. Totally happy with it.
Last summer in upstate New York we were in a valley with 1 bar or no bars of signal and had one place in the coach where we could maybe get cell service for phone call. Forget about internet.
The WeBoost took signal from 1 to 2-3 and actually was able to use the MIFI A bit on the pricy side, but in our opinion worth it. I have my antenna mounted on the rig ladder and ran the cable through the left side slide. Easy install.
