Episode 004 - Rich Fusinski - K8NDS
This is K8NDS theme and variation on the magnetic loop antenna. Instead of a solid loop, Rich winds flat copper strap around a helical form made out of PVC pipe. The surface of the flat copper increases the length of the antenna while keeping the whole antenna smaller and more compact. All of the benefits of a full size loop, but in a more efficient and smaller package.
