§ 27.63 Disturbance of AM broadcast station antenna patterns.
AWS and WCS 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 AWS or WCS 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 would affect the AM station
antenna pattern. The AWS or WCS 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 AWS or WCS 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 would affect the AM station antenna
pattern. The AWS or WCS licensee is responsible for the installation
and continued maintenance of any detuning apparatus necessary to
restore proper performance of the AM station array.
