Описание
The present document specifies the essential electrical requirements for circular polarization fixed beam antennas to be
utilized with Multipoint (MP) systems, including central station, repeater stations, and terminal station applications,
operating in frequency bands from 1 GHz to 11 GHz. These systems use various multiple access schemes.
Electronically steerable antennas, and linearly polarized antennas are not considered under the present document.
Where circumstances merit, and after a consultation period with operators and manufacturers, the Regulatory Authority
may impose the use of tighter requirements than the minimum values given in the present document, in order to
maximize the use of scarce spectrum resources.
