No one has claimed this so far. The Rp of a copper-wire suppressor can
be made even lower than the Rp of a resistance-wire suppressor by
increasing L-supp. The trade-off is increased dissipation in R-supp.
The bottom-line on resistance-wire suppressors is that they reduce the
10m dissipative burden on R-supp.

In Wes measurements, at 100MHz, Rp decreased from 166-ohms to 101-ohms
with the resistance-wire suppressor.
