Forget about Terk, it's overpriced and under performs. The first thing you need to do is figure out the distance and direction of your house from the broadcast towers you are trying to receive the signal from, this can be accomplished by typing in your address at antennaweb.org. This site will tell just how much antenna you should need to pick up your local stations. Keep in mind that having in the garage rafters (equivalent to an attic install IMHO) will reduce the antennas range by at least 40%. Because of this you want more antenna then suggested by antennaweb. For example: if you are 20 miles from the towers then buy an antenna with UHF performace rated at, at least, 35 miles. I was 25 miles from my towers at my old condo but needed an antenna rated for 60 miles to get all the stations (due to stucco walls with metal mesh and tile roof, most typical brick veneer, wood siding, etc, doesn't have metal mesh in the walls).
