Default The antenna of AC7JF?

Dear Ralph Mowery, KU4PT:

Spot on! Thanks.

Complicated antenna. Would be a big challenge to model.

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?

Probably this one:

A KLM-34A.

I am not sure why they went out of business, but they seemed to make good
antennas. I have the OSCAR combination of the 2 meter and 432 mhz
system.
