Log periodics are somewhat fiddly. > What about building a pair of yagis ( > http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf) and mounting > them on the same boom?

It works pretty well, but the antenna is fiddly to tune. I recommend tuning up each antenna separately, then fitting the diplexer and tuning that.
