I'm looking for an old AMSAT Journal article by Domenico Marini

"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.
