1、SMA Inner Needle Interface: The radio antenna has an SMA inner needle interface, and the omnidirectional high gain antenna reduces co channel interference and enhances the signal gain effect 2、Convenient and Practical: The radio antenna can receive data quickly, the gain is high and the range is large, the more open the distance, the farther. The interface is red copper inner thread inner needle 3、12DBI High Gain: The radio antenna has a 12DBI high gain signal, and the antenna base and antenna pole can be disassembled for easy cleaning 4、Adsorption Base: The base of the radio antenna is equipped with a magnet. The magnetic suction cup is convenient for fixing and can be adsorbed on metal objects 5、Applicable Equipment: Wireless monitoring, WIFI, BT module, smart home, product signal lights and other transmission equipment Item Type: Radio Antenna Material: Red Copper Purpose: Signal Transmission and Gain Working Frequency: 2400-2500mhz Antenna Gain: 12dbi Standing Waving Ratio: ≤1.5 Impedance: 50Ω Polarization Method: Vertical Polarization Maximum Power: 50W Antenna Interface: SMA Inner Screw Inner Pin Line Length: 3meters/3.3yd Line Type: RG174 Line Working Temperature: -40℃~+85℃ Applicable Equipment: Wireless Monitoring, WIFI,  BT Module, Smart Home, Product Signal Lights and Other Transmission Equipment 1 x Radio Antenna
