Welcome to our store! 1. HIGH-QUALITY MATERIAL: High-quality environmentally friendly ABS material, high heat resistance, flame retardant, durable. Makes the signal stronger. 2. PREVENT INTERFERENCE: Omnidirectional high-gain antenna reduces co-channel interference, improves signal gain, and enhances 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 select a better angle for the signal, and the side can be rotated 90°, which is more effective. 5. HIGH GAIN: The gain is as high as 3dBi, the transmission range is large, and the farther the distance is affected by the environment, the longer it is. 6. APPLICABLE: Widely used in security alarms, smart homes, power monitoring, network image transmission/security monitoring equipment, industrial status monitoring equipment, and network digital image acquisition equipment.
