Feature: 1. HIGH QUALITY MATERIAL: High quality environmentally friendly ABS material, high heat resistance, flame retardant, wear resistant. Make the signal stronger. 2. PREVENT INTERFERENCE: Omnidirectional high gain antenna reduces co channel interference, enhances signal gain, and improves transmission performance. 3. GOOD PERFORMANCE: Red copper inner core SMA gold plated connector, high conductivity, low energy loss, and better wireless penetration capability. 4. FLEXIBLE: The antenna adopts a flexible structure design, which can choose a better angle for the signal, and the side can be turned 90°, which is more efficient. 5. HIGH GAIN: The gain is as high as 3dBi, the transmission range is large, and the more open the distance is affected by the environment, the farther. 6. APPLICABLE: Widely used in security alarm, smart home, power monitoring, network image transmission/security monitoring equipment, industrial status monitoring equipment, and digital network image acquisition equipment. Specification: Item Type: Antenna Model: JB-2.4G/5.8G-008 Material: ABS+ Copper Antenna Gain: 3dBi Antenna Frequency: 2400-2500MHz/4900-5900MHz Joint Inner Diameter: Approx. 6mm/0.24in Outer Diameter of Joint: Approx. 10mm/0.39in Polarization: Vertical Polarization Standing Wave Ratio: ≤2.0 Impedance: 50Ω Working Temperature: 40℃~+80℃ Purpose: Signal Stabilization and Gain Scope of Application: Security Alarm, Smart Home, Power Monitoring, Network Image Transmission/Security Monitoring Equipment, Industrial Status Monitoring Equipment, Digital Network Image Acquisition Equipment. Package List: 3 x Antennas Note: Please allow some errors due to manual measurement.
