WellGood Loop HF antenna project by G8OCV & M1GEO (ver.1.1)
will work for receiving shortwave HF/SSB/AM radios
The loop on the original antenna was made using RG58, with the outer screen used as the loop, and the inner conductor not connected. This was then supported in a plastic pipe. Others have reported that their loops were made with a clip together metal ring. The diameter should be around 1 meter, and thus around 3.14 meters of material is needed to create the loop circumference. Ideally, you want for the loop conductor to have a largish diameter. A tube or coax screen will outperform a small piece of wire.
