[Boatanchors] Ground wire?

YEA! Copper "flashing" strip is the best! Better than wire, or the woven
"braid" although somewhat awkward to use at times. The thickness doesn't
make a whole lot of difference. 3" wide is the most useful and 2" is a
close runner up. The big problem is it is not cheap!
"Radials" (buried) for an antenna system can be wire or "old" coaxial cable.
RG-58, RG-59, RG-6 (if the braid is copper). Above ground "counterpoise"
radials can be #14, #12 or larger common insulated or bare single conductor
stuff.
Been using the 3" flashing for YEARS on personal amateur grounding setup,
and also on marine installations to "cool off" racks and cabinets even
though the steel members are joined securely mechanically!

Ideally none of what you mentioned should be used--copper strap 2 or 3
inches wide is desirable. But I understand you need a quick fix.
Copper is better than aluminum because with aluminum you have to
fabricate some sort of union between the rod and the wire. You can't
connect aluminum directly to copper.
