CITY OF HOUSTON
301.2 Exempt Work.
Exemption from the permit requirements of this code shall not be deemed to grant authorization for any work to be done in violation of the provisions of this code or any other laws or ordinances. An electrical permit shall not be required for the following:
8. Electrical wiring, devices, appliances, apparatus or equipment operating at less than 50 volts and not capable of supplying or controlling more than 50 watts of power.
That seems to exempt most antenna work from needing a license in Houston, though it makes me wonder about cable TV line amplification, since that has used 60 volts for decades, and some modern cable TV amps use 90 volts.
