Hello! I actually created a product, based on my need for Internet on the road, that may help here. It is a kit that comes with a high-gain antenna that has a built-in ground plane, so it can be mounted anywhere. I actually include a 3-way mounting bracket so you can mount it on a ladder, etc.
Then, you connect the antenna to a 3-watt amplifier (just like they use in the logging industry). The kit uses cellular networks as the backbone (Sprint, Verizon, etc.) but this is where it gets interesting...
The amplifier boosts the signal to the point that it has been tested to hold on to a cell signal another 40 to 60 miles beyond where you normally lose it. In an emergency, you can also use the kit to boost your phone's signal.
Then, I include a cable that runs from the amp and connects to the data card (from Sprint, etc.) Then, you plug the card into a mobile router (comes in the kit), and your RV becomes a WiFi hotspot floating down the highway. So now, if you have more than one laptop, you look for local networks, and you will be able to connect to your own highly secure network. You can also plug a networked printer in to the router, and print wirelessly.
Again, I created this product out of a passion for road trips, and a passion for wireless communications. I am happy to help answer any questions if anyone has any!
