Feature: 1. Material: ABS environmental protection material, first class production technology. 2. Fast Transmission: Independent channel transmission is faster, reducing co channel interference, enhancing signal gain effect, and improving transmission performance. 3. High Gain: The gain is as high as 3dbip, and the transmission range is large. The more open areas are affected by the environment, the farther the transmission distance is. 4. Wide Range Of Applications: 433M wireless meter reading system, LORA wireless data transmission module, drone, security alarm, power monitoring, smart home, etc. 5. High Performance: Excellent corrosion resistance, salt spray resistance, heat resistance and stability. Specification: Item Type: Antenna Material: ABS Model: JB-433-012 Purpose: Signal Transmission And Gain Antenna Gain: 3dbi Impedance: 50Ω Maximum Power: 50W Working Frequency: 423-443mhz Standing Wave Ratio: ≤1.5 Polarization Method: Vertical Polarization Antenna Interface: SMA Inner Screw Inner Pin Application Areas: 433m Wireless Meter Reading System, Lora Wireless Data Transmission Module, Drone, Security Alarm, Power Monitoring, Smart Home, Etc.. Package List: 5 x Antenna
