Actually, unlike Wullenweber, they have multiple concentric rings of
verticals in the array with a complex phasing system. My guess is that
this may have been a contributor to the methods eventually used in
phased array radars. But also something that was an engineering study,
and not necessarily practical.

Our Wullenweber at Hanza had two concentric rings of antennas, the high band
and the low band. And it did have a phasing system to form a beam. The
pattern was very sharp.

Oddly, most of what shows in a Wullenweber photograph isn't antennas, at
all, but the passive screens that give the array its characteristic of
seeing just off to one side. In some photos the ring of monopole antennas
can be tough to spot.

Unfortunately for this discussion, I didn't work in any of the DF shops. I
was in the Comm Shop -- crypto, TTY, telephone & mux maintenance. What I
learned about DF was just picked up along the way.

In this system all antennas were active, and all were quarter wave
verticals at the design frequency.

Still, must have been interesting and fun with the variety you got to
deal with.

Absolutely! My first duty station was an intercept site in the Philippines,
then Hanza, then sea duty on an admiral's staff (Second Fleet Commander).
There wasn't much I hadn't seen by the time I was 25. I made CPO the next
year and was dubbed "The Teenage Chief" for my youthful appearance.

I'm 66 now and smiling slightly, content at how well things have worked out,
thanks to that lucky beginning.

All that bright Mississippi Sun and heat and humidity around here,
sometimes when I am working in my yard, I see Sun Spots in my eyes.
I am 67, or maybe 68 years young, I don't know how old I am.
It's RUFF on me!

You're certainly welcome but I have to say I got as much out of it as I put
in. The training, experience, maturity and travel were incomparable.
(Living conditions far from cruise ship standards, but it was usually
comfy.)
