I don't have a picture of my setup but I use the following. I have a 20' Flagpole from flag pole buddy with WireEng WideAnt2-x Dual Antenna at the top. I've been able to reach out extremely long distances and get four bars in area's that have no signal at all. I also use a Cheap TP-Link directional WIFI antenna to pick up and re-broadcast camp WIFI for my family and friends. Works with website login and it's plugged into the WAN port on my MOFI router. This setup allows me to use campground WIFI if available supplemented with my cellular service or just my cellular service. The MOFI router also has fail over capabilities so what ever service is faster the router performs automatic switching to the fastest source. Works awesome and I love it but requires a little setup work.
you can find the antenna's cheaper but here is a link to the model.

This is my service provider UbiFi and you can get the router from them setup and ready to go.
