Best TV antenna for tailgate?

Late to the party here, wanted to remind OP that WAFB and WBRZ's actual channels are high-band VHF (9 and 13, respectively).

UHF-only antennas tend to have a problem picking up WAFB on campus. If you can fit it, pick an antenna that has at least one "long" element, such as THIS or THIS.

Both look like they are designed to be screwed into wood, such as on a roof fascia. You can always copy my friends' idea for their Dish antenna and stick a 6-7' pipe in an old bucket half-filled with Quikrete. I would wait until you get the antenna to properly size the pole. Unlike a satellite dish, aiming precision on a TV antenna is not nearly as demanding.
