   Hi pjp,   
      
   It's good that you can "see" something at the RV, as this stuff is line of   
   sight (LOS), where the distances are immense LOS, but they suck otherwise.   
      
   The way you get LOS in trees, of course, is to mount the antenna on the   
   tree (which we do all the time), and at home, the way to get LOS is you   
   mount the antenna on the chimney (which we also do all the time).   
      
   Or on a pole (which we do all the time too).   
      
   As long as you can see the antennas, you're good to go, where we can deal   
   with the Fresnel Zone later.   
      
   Once you have two antennas pointed at each other, all you do, physically   
   speaking, is connect the home end to Internet via Cat5 cable, usually to a   
   router switch but it could just as well be directly to the modem or   
   whatever you get your Internet from.   
      
   At the RV you have a couple of choices depending on what "device" is at the   
   RV, where you don't need anything else if you're going to plug the Cat5   
   cable directly into, oh, say, a desktop at the RV.   
      
   Often, if you're going to go to all that trouble, what we do is find a   
   spare SOHO router lying around (we have tons of them, as you can imagine),   
   and we just plug the RV antenna Cat6 into that "RV router".   
      
   That's the best setup, which gives the most flexibility at the RV end.   
      
   Essentially, you have the same Internet at the RV as you have at home.   
   a. At the RV, mobile devices can connect to the RV router   
   b. Laptops and desktops with WiFi can connect to the RV router   
   c. Desktops without Internet can connect to the RV router switch   
   etc.   
      
   Notice while my original "pool" example is only hundreds of feet of range,   
   so you can skip the second radio in the case of hundreds of feet - your "RV   
   example" is a kilometer, which is likely too far for more mobile devices   
   and laptops to send back to. (There are people here who can do the math   
   since all this stuff is well known to them - where there are web sites   
   which allow you to run the calculation.)   
      
   Without even running any calculations, you'll notice I'm suggesting a radio   
   & router on each end, because I know that works in all circumstances if   
   they can "see" each other (i.e., LOS).   
      
   There's lots of good stuff in any search where those are the basics:
