Dual polarity quad...possible to build?

[2RT307]

I have a PDL II in my shed, but never got around to putting it up. (I had been running a 4 element Yagi). Before I found the PDL, I stumbled across this site, which shows how to make one in a little different configuration, but the idea is the same.
