Hmmm. Copied from the second of the two hyperlinks above:
(ii) The other test is an Antenna- Mast System Test (§ 1204.4(e) of this subpart) which is intended to determine whether the means provided to protect against electrocution will withstand the stress imposed when an antenna-mast system falls onto a power line. This test consists of mounting the antenna to be tested on a specified mast and allowing the assembled antenna and mast to fall onto a power line of 14,500 volts rms phase to ground.
Only a fiberglass antenna will pass that test. This requirement is what started the rumor that metal antennas are "outlawed".
Only if they're sold as a consumer product.
