Query: Terrible

I bought this so that i could have a low profile antenna to help with my TVs reception. Before i got this I used a 3 foot piece of coax cable as a temporary antenna. I got OK reception but wanted a better picture. Using this antenna produced a worse picture than the piece of cable alone. I immediatly sent it back for a refund. Terrible product.
