Dave Holford article ...

^ I have personal experience, some 40 years ago, with an
^ HF antenna which consisted of the top half of the tail
^ (about a 15 to 20 foot square metal surface) which was
^ tuned by a remote ATU (Collins CU-351 ISTR) and performed
^ at least as well as a fixed wire over the range of 2.5 to
^ 30 MHz.

If I could put an antenna like that 20,000 feet over my house I would be very
happy indeed!

Worked very nicely between 50 and 100 feet, and very seldom were we
above 5,000. I am aware of it being used to communicate from Australia
to the East Coast of Canada while on the ground, and I have personally
used it to communicate to North America from Europe while on the ground
- never ran over 400 Watts.

Frank it's called a "sky hook".
