If you are withing 20-25 miles of the transmitting tower, this super
duper antenna works splendidly for capturing HD broadcasts:

I just tried an experiment for kicks.

I have a small, single pole antenna that I use on my receiver for FM
reception. It's half of an old rabbit ear antenna.

I hooked it up to my TV and did an autoscan. My house is probably
35-40 miles from the nearest transmitting antenna in Boston and the
single pole antenna is just sitting beside the TV. Autoscan found 7
digital channels.

Here's the antenna:

Here's channel 7 in Boston using the single pole antenna:

Here's channel 2 (PBS) in Boston (blur is due to slow camera shutter
speed. HD picture on TV is perfect):

Only goes to show that there's nothing magic about the revised and
modernized rabbit ears that are being marketed as "HD Antennas".

As an afterthought I just did another experiment.

We have Comcast cable TV and I have a HD cable box also hooked up to
this TV. I put the box on channel 7 HD and then compared it's picture
to the same HD programming being broadcast and picked up by the little
single pole antenna. (Switched "input source" on TV back and forth
between the two).

The broadcast HD picture using the antenna is noticeably superior to the
Comcast cable HD picture. Much clearer, much more "HD" looking.

Comcast compresses HD signals in order to get all their "stuff" on a
cable. The broadcast signal is the way it's supposed to look.

During a cable outage we connected a 30 foot piece of cable to the HD -
In and scanned for channels. We picked up about 20 or so. When I hooked
the old rabbit ears up we got about 25 and when I bought the "HD"
antenna we started to get about 60 or more channels. This included the -
1, -2, -3 and -4 channels for each old timey channel.

The OTA quality puts cable to shame.

I don't believe there is any difference between uhf/vhf antenna and a HD
antenna. They all use the same frequencies.
