433MHz Antenna 2-Pack SMA Male 3dBi Omni-Directional, High Gain Sub-GHz IoT

Product Information

About

EXTEND YOUR SIGNAL RANGE - Upgrade your 433MHz wireless devices with this high-gain 3dBi omnidirectional antenna pair. Boosts signal for remote controls, garage door openers, wireless sensors, alarm systems, smart home hubs, and LoRa-compatible IoT transceivers up to 700 feet.
TRULY TUNED AT 433MHz - Precisely tuned for the 433.05-434.79MHz ISM band with low SWR (<1.5), delivering stable, reliable RF performance. Gold-plated SMA-Male connector ensures corrosion resistance and consistent signal contact over time.
UNIVERSAL COMPATIBILITY - Standard SMA-Male connector fits a wide range of Sub-GHz devices and modules with SMA ports: RF transceivers, wireless receivers, IoT development boards, smart home controllers, and routers that support removable antennas. No soldering required for most devices.
COMPLETE KIT INCLUDES - 2 × 433MHz 3dBi antennas (11cm) + 2 × UFL to SMA pigtail cables (15cm, RF 1.13). Everything you need for quick installation. Ideal for upgrading devices with internal antennas to external high-gain performance.
VERSATILE USE CASES - Perfect for extending range on Sub-GHz wireless systems: remote key fobs, gate openers, weather stations, IoT sensors, security systems, and hobbyist RF projects. Note: for best performance, mount the antenna in a clear location away from metal surfaces and shield the SMA connector from interference.
