There is a great site for DIY antenna making for digital TV. The key
words are Gray-Hoverman TV Antenna.
I'm surprised that no one in a group of model builders and experimenters
has mentioned this.
I made a "single-bay" version using 22 gauge insulated wire, scotch taped
to a piece of cardboard, located in a second floor bedroom and facing out
the window. It gives me about 95% of what I want, and I'm located about 45
miles from Mt. Wilson, which is the location for most of the Los Angeles
TV station antennas.
If nothing else, the web site makes for interesting reading. The general
result is that the antenna that you make will not necessarily be much
cheaper than a commercially available one, but it's performance should
equal or exceed any commercial antenna. My version, of course, cost me
peanuts. The majority of the cost was for a length of coax and a 300 to
75 ohm impedance matching transformer - just a few bucks.
There are also web sites that give you signal strengths for your specified
location, and the direction to point your antenna.
