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! Frank |

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.
