Throw-out antenna type 411?
 

Unfortunately between nabbing it and getting it home, the
cardboard tag broke off and disappeared, but ISTR that
it said type 411

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.

Many of the Bush Pilots in Alaska, back in the day, used Longwire
antennas that had a cone, or funnel, on the External End, with the wire,
on a spool, that the Pilot could manually crank out and in. He would get
the HF Radio on a Frequency he wanted to use, then Transmit a low Power
Carrier, and un-Reel the antenna wire, until he had an Electrical 1/4
wave, and the reflected Power went to Zero. Then he could make his
Camms, and monitor the Freq, until it was time to land. If he forgot to
Reel in the antenna, before he landed, then usually he lost the trailing
wire. Yep, Been their, DONE that.... as have most Pilots that used that
type of Antenna. Later when they went to SSB instead of AM, they had
AutoTuners to tune fixed antennas on the aircraft. Just Say'en....
