Not verified, but speculating that steel wool (after a while) would act as a
bunch of diodes (corroded junctions), rectifying RF currents and generating
harmonics.
For monoband entennas I preferred 1/4 wave coax "bazooka" baluns. They widen
the B/W of antennas, also work as filters/stubs on single band and take power
without frying anything.
