I am using one that I built as I am just cheap lol. However it works great for now. But I agree Dee Ann I am putting up a tower (I already have it) then purchasing a decent antenna or two so i can pull in channels from further away. Great job on the build anything is better than nothing.
I love my radio shack that I deal with. Yes they are higher priced. However ours is owned by a Ham Radio guy and almost everyone that works there is lic. to operate Ham. They are very knowledgeable and carry lots of none raido shack brand stuff. Guess it all depends on who ownes the place.
