Cutting the cable, lets talk options and media setups

Anybody know anything about outdoor antennas?My dad is looking to hook one up @ his house . I know he'll need a mount or pole to put it on.
Will he just have to run it to his old cable hook up? Also,will he need a grounding pole as well?
Can Anybody share a little insight into this?

I put this one in my attic over my garage. I ran the coax to where my cable comes into the house and hooked in there so that it hits all of my tv's. I initially just had it standing on the floor of my attic but eventually mounted it one of the rafters to raise it a little higher. I don't think it made a difference in reception. I did have to purchase the mounting arm separately. I get ABC, NBC, CBS, Fox, CW, PBS, Bounce, and Create. I've found myself watching Create more than any other channel.
