ONE.Product function introduction
Product name: UHF four-dipole TV transmission antenna
Equipment model: ZRUHF-4O
UHF four-dipole TV transmission antenna is a directional plate antenna, which has the characteristics of wide frequency band, high gain, small standing wave ratio and flexible and convenient installation.
1.The configuration of the unit board can be changed according to the requirements of different service areas, that is, the horizontal pattern of the antenna array can be changed to give full play to the maximum benefits of radiation
2.
Different wave speed down tilt and zero filling can be adopted according to different service area requirements3.
It can cooperate with multiplexer to form a common transmission antenna system.The UHF four-dipole TV transmission antenna designed and produced by our company not only has high gain (G ≥ 12.3dB four layers and four sides), wide frequency band (470~860MHZ), low standing wave ratio (S ≤ 1.1), but also uses a glass fiber reinforced plastic cover (material is 191 # unsaturated resin). The antenna is waterproof, corrosion resistant, strong wind resistance, long service life, and its technical performance reaches the domestic leading level. The standing wave ratio of the antenna system meets the requirements of duplex and multi-purpose use. It is one of the first choice products of decimeter band TV transmission antenna.
All indicators of the antenna system comply with the standards of GY/T 5088-2013 Technical Indicators and Measurement Methods for Transmission Antenna Feeder System of TV and FM Broadcasting.TWO.
