Default The antenna of AC7JF?

Dear Group:

A long time colleague of mine, who was once my student and is now retired,
is also a great fan of antennas. While driving around Lake Havasu City, AZ,
looking at antennas - do we not all do that when we travel - he spotted (and
photographed) the antenna of AC7JF.

The antenna can be seen at: docpg.org

The antenna appears to have four, yagi style elements, to be feeding one
element with a second element connected to the driven element with a
transposed TL, and appears to be using stubs on the ends of the elements to
effect tri-band performance.

Hy-Gain uses a similar scheme on one of their verticals.

I think that I have seen this antenna before, but I can no longer place it.
Any suggestions?

It's a bit hard to see, but it looks like the feed (left to right in the
picture) is to the 2nd element with a crossed phase parallel line to the
third.
