Hi
Is it possible to get one of those wavlink like this

And put this on roof and run a ethernet cable in to the rv and plug it into a router in the rv and pick up the parks wifi just like you can with the proper rv-wifi (

If you get a router that will work with a 3g and 4g modem can you also mount a antenna for that on the rv and also pick up 3/4g too like the rv wifi you can buy that’s designed for a rv
