Folding Ground Plane.
Form your own conclusions. It works. Tested at 50W on 2M and 70CM.
This is the prototype. It is rough, very rough.
Made from a 16″ steel pizza pan found at Wal-Mart.
Purchased a piano hinge at Home Depot, cut it to length and riveted the thirds together.
Why did I build a folding ground plane? Why because I could, that’s why.
