It's always good to hear when something one does or writes inspires somebody else to try it and they are pleased with the outcome. Sivan, 4X6IZ, made a version of my portable Wonder Loop and found that "it works as advertised." He has put some information and pictures of it and another loop he made on a website. His idea of using polyethylene coated aluminium pipe to make a fixed frequency loop and tuning capacitor is particularly interesting if you always operate close to a particular frequency such as for QRP CW, PSK31 etc. If I had space in my attic for another magnetic loop I could dedicate for HF APRS use I would definitely make one of these.
I'm sure you'll find it worth reading about Sivan's magnetic loop antennas.
