Obviously, then, it can only be accomplished with
"Monstrous" oxygen free copper elements in the
antenna thus simultaneously broadening the band
width and the attraction for urban copper mining
while adding no untoward "coloration" to the
eventually demodulated audio as might be the
case with oxygen contaminated copper.
