These antennas are characterized by an ideally circular radiation pattern in horizontal plane and a gain coefficients of 3, 5,2 and 8 dBi correspondingly. The antenna A-3D is recommended to be applied as an inside-the-office antenna, while the rest of antennas - as the base antennas. The model A-8D has an increased gain and a tilt of the radiation pattern in a vertical plane what provides a maximum efficiency at receiving and transmitting the SHF power near the earth surface, where the subscribers are positioned.
