I would like to experiment with a 3m radius ground screen, laid on the ground at the base of the transmitter. I am wondering if anyone here has any ideas on an inexpensive way to create this easily and quickly; possibly with the ability to fold or roll it up when not in use (or when necessary to transport the system). Ideally the ground screen would be highly conductive, although it certainly does not have to be made of copper. I would prefer something that approximates a sheet as closely as possible rather than a rat’s nest of wires. I have used things like gutter cover and chicken wire for ground screens in the past, but they don’t really come in the right size and shape. Something like this would not only be useful for Part 15, but could also be used for ham radio (augmented, of course, with radial wires).
