I use and recommend 6061-T6 aluminum plate. Mine has been installed since
1999 and has presented no problems to date. Here is a view from inside the
shack:

The 1.5 inch copper braid ground strap has been replaced with 3 inch copper
strap. Here is another view, from outside:

Subject: [TowerTalk] Which grounding panel material?
Hi,
I am refurbishing my shack and want to place a grounding panel into the wall
and to bring all my antennas into the shack through it with bulkhead
adaptors. Just want some advice.
1. Is copper plate (say a 1cm, 1/3 inch thick) the best choice (say vs
aluminium)? I would drill holes into it for bulkheads.
2. Should I worry about the lightening setting my house in fire when the
plate is having direct connection with the wooden walls? We don't get so
much serious lightening actually and I am not intending to use the
polyphasers instead of bulkheads as well...
3. Does a large 10 square feet copper panel need extra warmth insulation in
winter, will it cool the house completely down in -20c otherwise?
4. Will the copper plate handle the weather fine and last long?
thanks for any insights,
73
