Captain Obvious here: I would run an ambient survey to see what's out there, and given a broadband antenna like that, you likely need a preselector to to protect from strong out-of-band signals.
If you have strong FM signals, you might want to consider a logperiodic that include the entire FM BCB so that the antenna can be oriented with the transmitter behind it to take advantage of a logperiodic's front-to-back ratio. A preselector only helps out-of-band, and you will need to measure in the FM-band. The above paragraph only really pertains if you have strong directionality in the broadcast. If your parking lot is in the middle of a city with buildings all over the place, that likely won't be the case.
