It may be related to both mechanical and electrical safety concerns since
the NEC (Sec. 810) dictates wire size irrespective of RF power level -- and
that the specified gauges are adequate for maximum authorized FCC power in
the amateur service. Perhaps the concern is with the feeding of a thin wire
radiator/transmission line with high power, and a portion begins to burn,
fall, then comes in contact with persons or flammable materials.
