The Razar and the jack are good antennas and are less directional. .. Put it up it works and most people find that as the definition of better . the batwing with wingman attachment is more capable of distance but must be pointed accurately and then moved if the other stations are in a different direction
120 miles for UHF is impressive and unlikely. I would think the salt lake station has a repeater in Moab ( it does) ;-) many small communities use repeaters and that's what your really receiving your siting right on top of the station
The jvcjeff post / study shows the differences very clearly .
