Dipole antenna for operation through a duplex filter on one feeder in the receiving (400-470 MHz) frequency ranges with preservation of the circular directional pattern. The antenna is an antenna array with increased gain, assembled on the basis of two dipole pairs united by an adder. Such a layering of several antennas on one mast increases the gain in reception and transmission at the same time.
