FCC 97.15(b) provides a limited amount of protection for Amateur Radio Operators who desire to erect antenna structures in the pursuit of their radio activity:
Except as otherwise provided herein, a station antenna structure may be erected at heights and dimensions sufficient to accommodate amateur service communications. (State and local regulation of a station antenna structure must not preclude amateur service communications. Rather, it must reasonably accommodate such communications and must constitute the minimum practicable regulation to accomplish the state or local authority's legitimate purpose. See PRB–1, 101 FCC 2d 952 (1985) for details.)
Local and state laws and regulations governing antenna structures may apply to amateur radio antennas as well, however they have to show a legitimate purpose for the rule that specifically precludes amateur radio antenna use.
