It's nice to see people post links and info on other designs. The original design I posted works very well for me, and there is no real opportunity to pick up additional channels in this area without some serious effort (investment), so I don't really have any need for a different design.
These antennas do work though... I don't miss cable at all. My favourite part is having the cable company call me trying to lure me back. They make me all kinds of freebies and offers, so I counter with ridiculous offers of my own. Last time, I said I'd sign on for the premium package if the installer cooked a pot roast with all the fixins for my family. Still no cable.
