5kw VHF Four-Dipole Television Transmission Antenna CH6-CH12

Product technical dataProduct name:VHF four-dipole television transmission antennaEquipment model:ZRVHF-4OEquipment origin:Jiangsu   Manufacturer:Confucianism Nanjing Radio and Television Equipment Co., LtdOne. Product function introductionThe four-dipole plate antenna is a wide-band television transmission antenna, which can work in the entire TV H l band, namely, 6~12 TV channels (frequency 167~225MHz). It has high power gain, convenient impedance adjustment and good standing wave ratio. The structure is relatively simple and convenient for processing and transportation. It can be conveniently installed on the side of various TV towers. By selecting an appropriate number of antenna dipole and its feeding method, it is convenient to Change the directionality of the transmitting antenna in the horizontal plane and vertical to meet the different service requirements of each radio station.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.
