On the way back to work from our lunch, me and my buddy saw a CPS Expedition slowly pass us the coming the other way on Nakoma by 281. It was driving down the middle of the road, barely staying on its side of the road, occasionally slowing to almost a full stop then moving up the road and slowing to a stop again. It was using the little tiny alternating white flashers in/by the headlights, but on the roof, where you would sometimes see a spotlight mounted, there was a log periodic yagi instead, rising about 6-8 inches above the roof top. The yagi's reflector(or rearmost) was about 14-16 in long and the front director was maybe 4 in long, not exactly sure what band this would be used for though.

OK. Question time. I was posting this because a) I have never seen a vehicle mounted yagi, or even seen pictures(though I haven't looked) of one; b) what would be the utility of having a vehicle mounted yagi like that, at least as far as putting it on a city/utility vehicle; and c) for the San Antonio folks, what exactly(or what do you guess) would City Public Services be using this setup for?

I might have gotten some pictures of this, but I didn't try very hard to convince my coworker/carpool driver to turn around.
