Also, consider the price of replacing it. I work at an RV parts store and we sold 5 Jack antennas this season to people who ripped them off the roof. All were due to low hanging branches, usually on a back road trying to get turned around. Some manufacturers are installing the Jack on the passenger side which makes them more vulnerable. In these cases, the Batwing would be cranked down.
There is a King Jack replacement head that mounts on the mast for the Batwing. If you're intent on a Jack, this might be a better choice. Signal strength meter available separately, or you can but a Sensar Pro.
