The only problem is the DIY version lacks the "cage" or wire "wall" behind the bow-ties that the retail versions have. I don't know the exact purpose of it, but I'm guessing it helps with rejecting off-axis signals and reflections, which makes an antenna much more effective.
Also... The retail version is only $40+s&h... so watch out how much you spend on this project... I'll do it just because it looks fun, but financially it's not going to save you much. http://www.starkelectronic.com/uhf.htm (first antenna on that page is basically the same as the one in this project)
