            Subpart C_Operational and Technical Requirements

 

Sec. 22.367  Wave polarization.



    Public mobile station antennas must be of the correct type and 

properly installed such that the electromagnetic emissions have the 

polarization required by this section.

    (a) Vertical. Waves radiated by the following must be vertically 

polarized:

    (1) Base, mobile, dispatch, and auxiliary test transmitters in the 

Paging and Radiotelephone Service;

    (2) Transmitters in the Offshore Radiotelephone Service;

    (3) Transmitters on channels in the 72-76 MHz frequency range;

    (4) [Reserved]

    (5) Control and repeater transmitters on channels in the 900-960 MHz 

frequency range;

    (6) Rural subscriber stations communicating with base transmitters 

in the Paging and Radiotelephone Service pursuant to Sec. 22.563.

    (7) Ground and airborne mobile transmitters in the Air-ground 

Radiotelephone Service.

    (b) Horizontal. Waves radiated by transmitters in the Public Mobile 

Services, other than transmitters required by paragraph (a) of this 

section to radiate a vertically polarized wave must be horizontally 

polarized, except as otherwise provided in paragraphs (c) and (d) of 

this section.

    (c) Circular. If communications efficiency would be improved and/or 

interference reduced, the FCC may authorize transmitters other than 

those listed in paragraphs (a)(1) through (a)(7) of this section to 

radiate a circularly polarized wave.

    (d) Any polarization. Base, mobile and auxiliary test transmitters 

in the Cellular Radiotelephone Service are not limited as to wave 

polarization. Public Mobile Service stations transmitting on channels 

higher than 960 MHz are not limited as to wave polarization.
