By black band I am assuming you mean the dark cross members at the top of
the reflector screen.  I can't tell from this picture.  It is an older
version of the array, but typically (all that I have seen) that is a piece
of lumber heavly treated with cresote and chemicals to preserve it from the
weather and bugs.  At the V7 and V8, Thailand and Augsburg) sites it is a
12"x12" (don't remember how long, and yes big and heavy).  Its purpose was
to support the reflector screen.  You can see in the photo along the bottom
of the top band the bolt that holds the verticle reflector cable.  There
were no horizonal cables laced or connected in the middle.  The gaps were
big enough to step through when I was younger.  Now that I am older and more
horizontally challenged it would be a tighter fit.  

I have worked at Augsburg, Project LIFETIME (V8) and Thailand, Project
KENWOOD (V7)

Fellows,

This would be inside the elephant cage on Okinawa. I recognize the concrete
buildings and the antenna. Roger

Those of you who have seen Wullenweber antennas, what is the black band that
joins the antennas? Thirty six antenna cables?

Bill Hawkins

--------
Bill the towers are just towers. The black band is just cable holding up the
antenna. Not seen in the photo is a screen of wire. You cannot even stick
your hand through the wire "mesh" if you walked up to it. Ok maybe you can
get your hand through it but you cannot crawl through the mesh. There is a
reason these are called elephant cages. They are in fact very big cages.
Some of the "skirt" does not reach the ground to make an entrance at one
point. 
The black band is not at the towers. The black band ring is larger than the
tower ring. Each tower has a cantilever arm sticking out that hold up the
black band ring. There is some "skirt" above the band ring that is free
standing wire.

Looks like these are your options:

a.. Augsburg, Germany
a.. RAF Chicksands, UK
a.. Clark AFB, Phillipines
a.. Elmendorf AFB, AK
a.. Karamursel, Turkey
a.. Misawa AB, Japan
a.. Ramasun, Thailand
a.. San Vito dei Normanni AS, Italy

a. Imperial City San Diego County on the silver strand.
a. Okinawa Japan

The one on Okinawa was about five miles north of and at right angles to the
main runway on Kadena Field. It sat on the high ridge of the island. I do
not remember it being visible from the roof top restaurant in Kadena City
(Okinawa City today). It may have been but at five miles it may have just
looked like a fence. The antenna field at Torri Station did not look
impressive from the roof top. You could not even see the SR 71's all that
well and they were only a couple miles away on the air field.

The runway is East / West. The west end is on the China Sea. The terminal is
on the south side of the runway. The Antenna would have been five miles
across the run way to the North. The antenna was not visible from any where
on the ground until you got up on the ridge and almost on top of the site.
It was all mask by vegetation.

Some of you pilots may have seen the antenna landing or taking off from
Okinawa. Mostly flights come over the island and over the antenna then did a
loop over the China sea and landed on the runway. This keep planes from
breaking glass in Kadena City at the East end of the runway.
