It's a Doppler style VOR. Which tend to be much larger than a conventional. Now why they elevated it so high... Possibly for aesthetics cause it's at the entrance of the airport, in public eye and it's TEXAS! Everything is big in TEXAS! Right?!? But more than likely it's so high so that the vehicular traffic doesn't interfere with the signal.

I think PHLapproach called it right. They were worried, and rightly so, about the traffic on the parkway interfering with the signal. Even for a normal doppler VOR, the cleared area around the facility has to be of a significant size. You can have obstructions, and most of the time it will be OK, but it's hard to predict beforehand just which obstructions can be safely tolerated. A couple of freight containers in the vicinity can muck up the signal. Now, imagine a traffic jam on the parkway full or trailers loaded with who knows what?
Also aesthetics, obviously.

I thought I was doing good trying to avoid those airport hotels... and look at me now.

Would you actually believe that that is actually just a bunch of classrooms?
Doppler VORs are gaining in number, but you'd be surprised at just how many important VORs are still on the old non-doppler, such as Wasatch (TCH), and Daggett (DAG). Heck, there's even new installations using the old equipment that the dopplers replaced (such as the Low VOR (St. George - UTI) at the new St. George municipal airport, which was installed about 2 years ago.
