Anybody have a good antenna design for the new UHF digital TV
stations?

I get reasonable results from my old VHF/UHF antenna (55% signal
strength) , but it's big and ugly, and I want to replace it with a
smaller, more efficient UHF design (maybe a Yagi) I can construct at
home.

Rule of thumb: The bigger and uglier the antenna, the better it works.

Anybody know the dimensions of such an antenna,

Various commercial digital TV antennas:

with Eznec NEC2 files at:

probabaly in the
frequency range of 400-800 Mhz ?

There are going to be some DTV stations in the VHF range. You might
want to check the new channels for your area:

Note that the upper end of the UHF TV band will be channel 51 at
698Mhz.
