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
