[TowerTalk] Name this antenna

[steve d]

I drive a truck part time and came across this (http://i118.photobucket.com/albums/o117/KC8QVO/random%20stuff/IMG_2427.jpg) antenna on Rt. 227 in Leesburg, VA on my trip the past couple days. Does anyone know whos it is and what it is for??? It is a log periodic and is the largest rotatable antenna I have seen with my own eyes. The main boom for the antenna is made out of triangular tower sectios. It appears to be about 70 - 100' in length, from the perspective I had on it. 
   
  The funny thing is.. I looked it up on google maps. You can actually see the antenna and the shadow it, and the tower it is mounted to, cast on the land HI. Pretty darn big! (I dont see the two other utility towers in the sat view, they must be new). http://maps.google.com/maps?f=q&hl=en&geocode=&q=leesburg,+VA&ie=UTF8&ll=39.102961,-77.543301&spn=0.002893,0.005021&t=k&z=18&om=1
