I read somewhere that you can use an antenna to pick up your local stations broadcasts even the ones in HD. My dad wants to see the Superbowl in HD and I remember reading that an antenna is the cheap way to go about it. Can any of you fine people recommend an antenna? My dad probably won't spent any more than $20-$40. Do any of you have any tips for a quality antenna (that can be picked up at your local BB, RS, Target, HD, etc.) and how to set it up for optimum recieving signal clarity?
