For those looking for a OTA HD antenna you don't need to invest a major amount of money for this. You can build one for about $20 dollars. All the antenna is a UHF antenna. Right now 99% of all HD channels are transmitted on a UHF signal. I had purchased one from best buy for about $150.00 and it didn't work very well. The one I built gets every HD channel and is alot stronger signal than the purchased one.
