Active 3-30 MHz Hula-Loop Antenna for Shortwave

I found this site a interesting hf loop antenna.

Antennas


Home-made antennas can greatly improve the performance of AM and FM radios,short-wave receivers, and scanners. If you are a talk-radio fan then experiment with the AM band antennas and you will be able to hear shows from all over the country with surprising clarity. Short-wave receivers are always coping with weak signals and they must have a good antenna to perform adequately. Scanners can pick up local police and two-way radio with the little telescoping antenna provided but with good antennas a scanner becomes an amazing ear on the world nearby. No pre-amp, filter or other receiver refinement offers anywhere near the level of performance improvement t that a well-designed antenna offers. The results can be quite satisfying, leaving no doubt that the project was well worth the effort.
