E1B07§ 97.15E1B →

To what type of regulations does PRB-1 apply?

  1. AHomeowners associations
  2. BFAA tower height limits
  3. CState and local zoning
  4. DUse of wireless devices in vehicles
Why PRB-1 is the FCC's 1985 declaratory ruling, reflected in 97.15(b), that limitedly preempts state and local zoning ordinances affecting amateur station antenna structures. Such regulations must reasonably accommodate amateur communications and represent the minimum practicable regulation to accomplish the community's legitimate purpose. It does not eliminate local rules, it just requires that they accommodate ham radio rather than ban it outright.
Watch out Homeowners associations are the tempting choice, but CC&Rs and deed restrictions are private contracts, not government zoning, and PRB-1 has never been extended to cover them; FAA/FCC antenna height rules near airports are a separate matter under 97.15(a).
PRB-1 = Preemption of Regulations By government (state/local zoning), not private HOA contracts. Think "reasonable accommodation."
HamSandwich explanation, first draft. The question and answers are the NCVEC text.
47 CFR 97.15 Station antenna structures.

(a) Owners of certain antenna structures more than 60.96 meters (200 feet) above ground level at the site or located near or at a public use airport must notify the Federal Aviation Administration and register with the Commission as required by part 17 of this chapter.

(b) 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.)

(c) Antennas used to transmit in the 2200 m and 630 m bands must not exceed 60 meters in height above ground level.
