It's probably not actually all that important.

Thanks for your comments and evaluation of the project. They are helpful to
someone not skilled in the black art of wireless :-)

I plan to modify the design a bit, eliminating all coax connectors &
adapters, using just 2 banana plugs (and supporting plastic block) as the
connection to the meter.

Is it any more efficient to use copper foil or PCB material as the reflector
rather than wire?

Thanks.
