I live in Shorewood WI, on the outside of Milwaukee and i was wondering, what is the difference between an HDTV antenna and an off-air HDTV antenna?
Answer
Television antenna technology has been around for 60+ years. Tried and true. Physically there is no difference you will still pick up broadcast signals either digital or analog.
I have the one listed in the link below installed in my attic with about 100ft of coax to my receiver. I pick up 18 OTA channels. and the uncompressed HD quality is outstanding, (not to mention it's free!).
I've also provide a link to a site that if you input your address it gives you a list of what channels are available in your area and the compass direction of where to point the antenna.
Remember, television waves travel in straight lines rather like light rays and do not bend much around obstacles. Consequently, wherever you live, your receiving antenna should be as high as possible and in the clear, so that it gets the best direct signal from the broadcast tower.
Reflected signals, also called multipath signals, from hills, tall buildings, trees, etc, arriving at your antenna a tiny fraction of a second after the direct signal from the transmitter will affect the signal. Trees and their leaves reduce television signal strengths, and create complicated reception patterns around your antenna. Trees both attenuate and reflect radio waves, (due to the water and moisture in them). So depending on signal strength, distance from the tower and amount of trees and foliage will all determine how much success you will have.

High quality HD over standard antenna??
Nic W
Today, on the radio, I heard that HDTV of standard channels (ABS, CBS, NBC, FOX, PBS) is broadcast free of charge over standard "Old fashioned" TV antennas.
This reputable radio host also mentioned that this form of HD was actually BETTER than cable or satellite because it was not compressed format.
Anyone know anything about this? Also, is there a way of taking advantage of this broadcasting without the "Roof mounted" antenna? Like maybe rabbit ears or something?
Answer
Yes, it's true.
DTV (including HDTV) is already broadcast in most of the US.
And DTV uses the same antennas as the old analog system. Some people will need better antennas though; DTV can be fussy about signal quality. If you already get good analog TV reception, your current antenna is probably good enough.
You can use any old TV with a cheap converter box to receive HDTV signals, but you will only see a DVD quality picture because that's the best that analog TVs were built to display.
To see HDTV broadcasts in "HD" resolution, you need one of the following:
A HDTV (includes ATSC tuner)
A "HD ready" TV and an external ATSC tuner box
A computer equipped with a SVGA or better display and a ATSC tuner card or USB tuner.
