AIUI, this is a throw-away antenna that was chucked out the back of an
aircraft to give HF coverage in flight.
It has a spring clip at one end, and a fastening at the other.

It is a 5" dia coil of what looks like Litzendraht (sp?) , estimated 100
turns,
and is tacked up by string in the manner that was used by lacing cord.

It is unused.

Anybody out there with the gen on it, please?

What's the question?

I remember one article in "73" about aeromobile and he said something
about just along length of wire with a weight at the end, that he could
unspool. Let it unwind and watch for a decent match, or something like
that.
