I just purchased a condo on 1st floor and also just purchased a 47" Sony LED Internet HDTV. Can I buy a small multi-directional outdoor antenna and attach it to the top of my patio fencing outside to get all of my local channels clearly? The prior owner had a satellite provider and the small satellite dish is already placed on the top / side of my patio fencing. I am trying to avoid paying costly fees for cable or satellite services by purchasing the outdoor antenna to watch my local television programming. Thanks !
