FIELD: radio engineering.
SUBSTANCE: invention can be used at basic stations of cellular radio communication network in order to provide signal emission with switched polarisation, and namely possibility of setting linear vertical polarisation, linear horizontal polarisation or circular polarisation of right or left rotation, when using stationary antennae of basic stations with cross polarisation, i.e. with double +45° and -45° inclined polarisation. Device includes in-phase equally amplitude power divider, two switched phase shifters having fixed values of entered phased progressions, which are equal to 0°, 90° and 180°, and three identical Y-circulators.
EFFECT: creation of the device allowing to receive switched polarisation of emitted signal when using stationary antennae used at basic stations of radio communication network, including multirange ones with cross polarisation.
