Dave,
I posted the pics of my old Ramsey shielded loop from '05 plus a couple of later creations in my John's Stacked Toroid Loop photo file. They are a final version of my Stacked Toroid Loop as a Palomar amplified loop head and a 7.5" FSL. Both designs from Everett Sharp. Both work extremely well on LW and MW.? Litz would probably help the Ramsey as well a close winding it as well..
John.
