I'm looking for an old AMSAT Journal article by Domenico Marini I8CVS titled "Switching Four Polarizations on a 70cm Crossed Yagi." I looked up Domenico to ask directly but learned he is a silent key. If anyone could send me a PDF, or guide me to where I might find an archive it would be greatly appreciated.
Also interested in any feedback on mounting yagis in an X-configuration and using horizontal polarity for VHF contesting plus other polarities for satellites. Minikits offers a kit to do the switching, apparently inspired by Domenico's design.
