3dBi 2.4G/4G RP-SMA Male Omni Directional Antenna

3dBi 2.4G/4G RP-SMA Male Omni Directional Antenna is a compact and versatile communication component designed to significantly enhance wireless signal strength for IoT devices, routers, and wireless modules. This antenna operates effectively across the 2.4 GHz and 4G frequency bands, providing a reliable 3dBi gain to expand your network’s coverage area. Furthermore, its omni-directional radiation pattern ensures consistent signal reception and transmission in all horizontal directions. Consequently, you can achieve more stable data rates and reduced latency without needing to precisely align the antenna with the signal source. Therefore, integrating this antenna into your wireless system represents a cost-effective way to overcome signal interference and physical obstructions in residential or industrial environments.

Key Features:

• Dual-Band Compatibility: Supports both 2.4 GHz Wi-Fi and 4G LTE frequency ranges, allowing for broad application across different wireless standards.
• 3dBi Signal Gain: Provides a moderate gain boost that increases the effective range of wireless modules without introducing excessive noise.
• Omni-Directional Pattern: Radiates and receives signals in a 360° horizontal plane, ensuring maximum flexibility in device placement.
• RP-SMA Connector: Features a standard Reverse Polarity SMA male connector, making it compatible with most Wi-Fi routers and RF development boards.
• Adjustable Tilt: The integrated hinge allows the antenna to rotate and fold, however, it maintains a rigid position once set to your desired angle.
