Alan,
I don't know why anyone would want to use copper braid for a ground
connection anyway unless the connection had to be very flexible, since even
clean shiny braiding compacted together with a cable lay has about 3-4 times
the RF resistance of a similar solid conductor. Of course dense weaves and
dirty braid is much worse, a typical braid off RG-8 cable after some age
with loose lay has about the same RF resistance as a #12-16 solid copper
wire.
I wouldn't think the copper plated strap (if it is real copper) would be
anywhere near as bad as braiding. maybe someone here has measured some.
