Sec. 22.371  Disturbance of AM broadcast station antenna patterns.



    Public Mobile Service licensees that construct or modify towers in 

the immediate vicinity of AM broadcast stations are responsible for 

measures necessary to correct disturbance of the AM station antenna 

pattern which causes operation outside of the radiation parameters 

specified by the FCC for the AM station, if the disturbance occurred as 

a result of such construction or modification.

    (a) Non-directional AM stations. If tower construction or 

modification is planned within 1 kilometer (0.6 mile) of a non-

directional AM broadcast station tower, the Public Mobile Service 

licensee must notify the licensee of the AM broadcast station in advance 

of the planned construction or modification. Measurements must be made 

to determine whether the construction or modification affected the AM 

station antenna pattern. The Public Mobile Service licensee is 

responsible for the installation and continued maintenance of any 

detuning apparatus necessary to restore proper non-directional 

performance of the AM station tower.

    (b) Directional AM stations. If tower construction or modification 

is planned within 3 kilometers (1.9 miles) of a directional AM broadcast 

station array, the Public Mobile Service licensee must notify the 

licensee of the AM broadcast station in advance of the planned 

construction or modification. Measurements must be made to determine 

whether the construction or modification affected the AM station antenna 

pattern. The Public Mobile Service licensee is responsible for the 

installation and continued maintenance of any detuning apparatus 

necessary to restore proper performance of the AM station array.
