If you mean can you point the satellite dish at the Garner antenna farm (where most of the local area TV station transmitters are physically located on towers) and pull in OTA broadcasts, then probably no.
That's because the satellite dish is sized for the carrier frequency of the particular satellite it's designed for, not for OTA reception.
You're going to need something more like a Channel Master 4220
(a two bay bow-tie style UHF antenna, other completely different designs work about as well). How big you need (2, 4, 8 bays depending on how much signal you need) depends on how far away you are and how good your "line of sight" is toward the transmitters.
As Wendy advised, websites like AntennaWeb.org are your friend. Not great user interfaces, but when you figure it out they will tell you the important information like which direction to point you antenna and how big an antenna you really need. Invaluable information.
If you want to pickup channels that are not located in the Garner antenna farm (like Chapel Hill's channel 4) you're going to probably need an antenna rotor like the Eagle Aspen ROTR100
to point your antenna at the appropriate transmitter.
For the record, I use both the products I supplied URLs to, and find they work great in the RDU area. And no, I don't have any ties real or imagined to either company beyond being a happy customer.
As far as where to buy all the necessary accessories to mount an antenna on your roof, in your attic, etc. Wendy again points you to one of the biggies in Summit Source. Pretty painful user interface that's difficult to search and find things, but they are pretty complete.
is a local (NC) company that has a lot of wiring and fixture stuff also. When I've bought stuff from Scott I've been impressed by his fast service. Again, no connection other than being a happy customer.
If you have questions as you go, this is one of the places to ask them. Often a pretty responsive group given how location specific it is.
