I use 24" wide copper flashing material available at building supply houses
and layer it onto plywood. I then have some 5" coax feedthroughs I picked
up at a flea market going through it. The copper panel then replaces the
lower half of my window in the shack. The plywood/copper panels sandwich
a piece of rigid foam building insulation.

You might also want to consider using aluminum sheet, or mounting the
thinner copper on a same-size sheet of plywood for structural strength.
