This may (or not) help
https://ebay.to/30OevAlI used to mount mine on a flagpole (height so it sees OVER the competition (Other RVs) and it worked rather well. I had a home router in the RV. (Cat-5 connects) It worked so well people 1-2 rows CLOSER to the router. if I liked 'em I gave them the "Guest" pass key to my router (It offered a guest account)
I have a fairly decent security setup here when I need to do it
I also used an old Linksys WGA-54G (Wireless Game Adapter) and the can described in Amateurlogic.tv's episode #3 George and Tommie later went on to improve it in a later episode I thought about it . .. but never did it
One note: Some routers my nano-station did not like,
