Yes. In fact, the weBoost RV4G booster includes a Yagi antenna. But remember, since the Yagi is a directional antenna, you need to re-aim it at at a cell tower each time you change location. So first you would have to find out where your carrier's tower is located from wherever you are parked.
Also, if you have a pickup camper or a motorhome, a Yagi antenna will NOT provide any cell coverage while you're on the road. It would only work when you park, assuming it's aimed properly as noted above.
