OTA digital TV broadcasts use the UHF frequencies, thus HD TV antennas do not need the VHF rabbit ear component.
I have been using indoor amplified HD antennas for about six years with great success. I get about 50 channels here in Houston and the local CBS' affiliates three channels/sub-channels are the only ones I consistently have problems receiving.
If I could put the antennas in a window I'm sure I could get better reception. The flat panel antenna under my desk feeds a TV turner card in my computer. That antenna was about $35 at Home Depot. The smaller antenna on top of the bookshelf feeds a dedicated HD TV and was about $35 at Sam's Club six years or so ago. I find OTA broadcast supplemented with online streaming is all I need. If you can put up an outdoor HD TV antenna and are a reasonable distance from the transmission tower you will most likely be shocked by what you can get for free OTA.
