Australian radio amateur Peter Parker (VK3YE) has experimented extensively with what he calls "pedestrian mobile antennas."  These antennas can be used either in motion or in a fixed location at a beach or public park. In this video, Peter explores a simple, practical pedestrian magnetic loop for the 40 meter amateur radio band (7 MHz). Peter compares copper and aluminum magnetic loops of different construction for their ease of operation and efficiency. Several of his magnetic loop designs have reached out between 300 km/185 miles and 1500 km/930 miles.  In Peter's view, "Tests demonstrate that HF pedestrian mobile with easily carried antennas is both effective and practical." Before you build and use these innovative antennas, please be aware that you may be exposed to excessive radiation near the transmitting eleme...

Here's another fascinating video from Peter Parker (VK3YE).  In this post, Peter shows us how to build a magnetic loop HF pedestrian mobile antenna for the 40 meter Amateur Radio band.  Peter compares copper and aluminum magnetic loops and shows how to adjust them for maximum performance. According to Peter, "Stations worked were between about 300 and 1500 km distant."

Peter Parker (VK3YE) has produced some excellent articles on pedestrian mobile antennas.  This video is one of Peter's earlier efforts where he designs and tests several magnetic loop antennas for mobile and emergency use.  Although Peter contends that "most HF pedestrian mobile activity seems to be on 14-28 MHz, where it's easier to build an efficient portable (antenna)...due to its activity and propagation, 7 MHz is also an excellent mobile band."  In this video, Peter compares copper and aluminum magnetic loops for both 80 and 40 meters, and makes a few interesting contacts in an afternoon of pedestrian mobile operations.  For more details on Peter's magnetic loop antennas, please visit vk3ye.com For the latest Amateur Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.ar...
