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 have this one inside my attic but I couldn't get all the channels well. I am about 50 miles from the towers in my area. So I moved it outside with no issues at all.
