cellular antenna. It has worked very well.
It is mounted on an 8 ft. PVC pole located on our ladder using Flag Pole Buddy pole mounts.
We use an ATT hotspot for our wifi in and out of the camper. When inside the camper we put the hotspot about 1-2 feet away from the weboost inside antenna and everything works fine.
Enjoy the road. We do.
