Re: [TCML] RF Grounding

["Peter Terren" <pterren@xxxxxxxxxxxx>]

For my TC for the Physics Dept, I used a ground plane (counterpoise) made 
from a large aluminium sheet. It also has a rather coarse Faraday cage but 
probably not essential.
It also has a mains earth or separate earth wire if a terminal is available.
