Welcome to the Sitesafe AM Tower Screening tool!
New Federal Communications Commission (FCC) Disturbance of AM Broadcast Station Antenna Patterns rules are in effect as of February 20, 2014. Compliance distances (generally less than the previous FCC rules) and a new structure height requirement are implemented in the screening. Please see our AM Disturbance Rule Change white paper. A copy of the new FCC rules are here: FCC Rules
The antenna structures of wireless sites can alter the antenna radiation patterns of nearby AM broadcast stations. The FCC requires that at the time of new structure construction or significant modification of existing sites, wireless operators demonstrate that their site(s) do not adversely affect the patterns of nearby AM stations. The FCC mandated zone of required protection is a radius of 1 wavelength determined by the AM station’s frequency for AM stations using non-directional antennas (single AM towers), or a radius of 10 wavelengths or up to 3 km whichever is less for AM stations using directional antennas (multiple AM towers). All towers detuned for AM station(s), regardless of distance, are regulated and the detuning equipment must be maintained and in proper adjustment.
In order to ease the "AM Screening" process, Sitesafe has created this free screening service.
