Digital TV booster-Who makes one?

I made my own tv antenna for the house. just google dtv dys antenna. this thing cost me $4 bucks and works so good I had to make six more for my buddies that didnt have cable. I put it in my old lady's closet in the top corner and hooked it up to the cable for the cable tv that run all over the house. we have three tvs hooked up to it and get stations up to 60 miles away. You could put one in your truck, or hang it on the back of the cab super easy. it looks a lot like cat whiskers. I made it out of a ten foot piece of romex. when i get a chance i will post some pics of it. i think i may try to make a bigger one some day but this one works so good i just dont have much motivation to do it. again i have to say this thing works like a champ. $4 bucks!
