Was there a reprint or some other record of that testing, Russ? My present vintage loop (it's Nelson's alt-az design) seems pretty well balanced per direction finding accuracy and symmetry, and the nulling is good, but I was surprised at how well a Sanserino 2' loop compared in nulling when I had them side by side 30+ years ago. There was never a proper record of that comparison however. best wishes, Nick ***************************** Nick Hall-Patch Victoria, BC Canada _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
