Query: Junk Junk Junk

Seemed easy enough, installed it in less than 10 minutes. It only works when you are right on top of the antenna (1 inch away) and even then, it only works about 1 out of 10 tries. I tried changing the frequency about 10 times, each time with the same junkie results. You get what you pay for!
