This one could be an option to get a good cell signal and from there you hook up to your hot spot off of your phone. Lots of reviews in Youtube. It is expensive. Easy to install and does boost your signal 50dB but you have to do a little homework before you get to the campsite to know where the closest cell tower for your provider is located. There is an app called OpenSignal that gives you the bearing on where the tower is located. Then, if you and your wife have different carriers, you will have to do the same with her carrier. Many times those towers will be located on different bearings. All this is to eliminate the guesswork of orienting the antenna to pick up the cell signal once you are at the campsite.
A booster can't make a cell signal out of nothing. There are limitations with this system. Your antenna has to pick at least a very weak signal to amplify it. Most of the time you will not be able to pickup a cell signal from your phone but when you install this directional antenna on the 25ft. mast it DOES pick it up and amplifies it.
A challenge to overcome if you want to stay married and not be sent to the doghouse is to keep her connectivity if you have yours. Since I decided to stay married, I turn the antenna (it is a directional antenna for maximum gain) for my device once she is done with her emails/texts/phone calls. Keep in mind that if you leave the system running all the time it draws about 0.5A @ 12DCV.
It is not the best solution. I am sure other folks have different opinions about this issue.
