I've hit the books for a new design which will probably include low-loss open wire transmission, an array of either loops or dipoles and some kind of reflector elements or screen. In the mean time, I'm creating more custom cut loops for the rest of the frequencies until the new design is resolved. Here I go again, wish me luck. To my surprise these are performing better than anything used previously. I'll try to let you know what happens this weekend.
Life goes on.
I also invite anybody to contact me if you have any questions about what I'm doing. I've started cutting elements for a UHF antenna array of constructed of very many stacked elements similar to the bow-tie arrangement you see on the main page. Worst case is I can switch between elements for different parts of the sky without moving the antennas. Oh, well, at least it's cheap. We're also trying to follow concepts written in The American Radio Relay League Handbook for Radio Amateurs.
