There is no such thing as a 720/1080i/p antenna - any antenna can receive OTA HD signals. More than likely you will need an amplifier and a larger antenna thou. antennaweb.com is an excellent resource to see what you need to get service in your area. I used that site then went to eBay and bought one of thoes 100 mile amp antennas. It was kinda junky but works great - it was around 60 dollars shipped. In retrospect I think I should have spent a few more bucks and got a nicer antenna.
