A few days ago I loaded up a football goal post as an HF transmitting antenna. I made a couple of contacts on HF. Coupling was via a Rowland Ring. This time I'm using one with a pier railing about 40m long. It's quite a good HF receive antenna, with quite low noise (even though homes and shops are a few hundred metres away). More in the video below.

Very interesting I have been in antenna s for most of my life but very heard of a rolling ring antenna.
