PART 22--PUBLIC MOBILE SERVICES--Table of Contents
 
            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.
