reasonable range for local wifi like campground/RV park, don't have a distance.
the antenna is mounted outside and the cable runs to the router inside the RV. I went thru the bath fan cover and to a cabinet. I actually mounted antenna to the TV antenna arm. The outside antenna was always there but lowered while traveling.
The router was above the kitchen cabinet. The router needs 110vac.
The Techno RV guys have a local computer desk model also, connected straight to laptop, but somewhat limited in use---no wifi other items.
