This is a discussion on Does my HDTV need an antenna? within the DTV | HDTV Reception and Antenna Discussion forums, part of the Over-the-Air (Antenna TV) category.
Why yes, it does need an antenna. What you need depends on where you live. It could be as inexpensive and simple as a $10 indoor antenna, or you may require a big roof top antenna - but for most people, it costs less than $50.
Please go to TV Fool and enter your address and planned antenna location. It will generate a report. At the top of the report is a link in bold type; copy and paste that link back here and we will tell you what channels you can get, and help you select an antenna.
You will need an antenna!!! If you will post the URL for your TV Fool report, we can help you pick out the antenna you will need. Your personal information will be hidden for your protection.
Once you have your antenna, you will point it toward your TV stations, connect it to the "Antenna/Cable In" coax connection on your TV, go into the menus on the TV, set the input to "Air" or "Antenna" and scan for channels.
Since you're 10 miles from most of the transmitters, have you tried an indoor antenna?
What kind of dwelling do you live in? House? Condo? Apartment? Do you own or rent?
Reason I ask is because even with transmitters close by, indoor antennas are a crap shoot. However, if you can get a small antenna up on the roof (basically any small combo VHF/UHF) you should have solid lock on all the networks.

Zenith ZHDTV1 HDTV-UHF Digital Indoor Antenna (Silver and Black)
I have always liked the Zenith Silver Sensor ZHDTV1, but I don't see it mentioned very often. I think the Phillips PHDTV1 replaced it. Now it looks like there are different variants of this. Some with VHF elements and some without. Also, some with a built in amplified and some without. SDV2780/27 Philips TV antenna SDV2780 Indoor UHF/HDTV digital - Philips Support
