Wide-band TV broadcasting UHF antenna with horizontal polarization “Zigzag»

Antenna is used for TV broadcasting of 470-702 MHz range and 574-860 MHz range. They are supplied assembled and adjusted to required operative channel. This antenna is a multilevel compact structure made of zigzag radiators.

Antenna is set at the height of the bearing, roofs of the high-rise building. It is possible to set antennas at the areas and bands of bearing metalware with appropriate directional characteristic. (DC).
