Roy,

Would you share with us which ones you think would work better?

Sorry, it's been nearly 20 years since I went through the patents, and I
don't recall all the various modifications and innovations I came
across. And I don't have any idea which might have been included in
commercial designs. Surely someone has done some comparative
measurements of various commercial units and published the results. If
not, it sounds like a good project for someone interested in using
through-glass antennas. I'm not one of them.
