Yep. I know the mount you speak of for the spare tire as well. Check out the Jeep forums and see what most suggest for a good antenna. Height is might, but you need some metal in the right place to make most antennas work correct. This is mobile antennas anyway. Breedlove mount you can't go wrong!! They are well made!! Have one and so do a couple of others I know. All are well built.
