Wireless small antenna 3dbi SMA Male

Choose a compact 3dBi antenna for stable telemetry of your drone

This antenna is not tied to a specific brand. This is a universal 2.4 GHz antenna. Manufactured by different companies to common specifications. Used in telecommunications, robotics and FPV.

• Low VSWR ≤1.5 for efficient power transfer.
• Compact length of 10.5 cm for easy carrying.
• 3 dBi gain for a stable signal at medium distances.
• Omnidirectional pattern for communication in any direction.
• SMA male connector for standard connection.

How does a 2.4 GHz omnidirectional antenna work?

The antenna emits radio waves evenly in all directions of the horizon. The 3 dBi gain concentrates the energy slightly to increase range. The signal is stable when the object moves. You get reliable reception at a distance of 100-200 meters.

Technical characteristics and functionality

The model has a standing wave ratio (VSWR) of no more than 1.5. The gain is 3 dBi. Operating frequency range 2400–2500 MHz. Omnidirectional radiation pattern (OMNI). SMA male connector (male). Characteristic impedance 50 Ohm. The total length of the antenna is 10.5 centimeters.

The antenna is suitable for ELRS, ExpressLRS, Crossfire receivers. Used in drone ground control stations. Improves telemetry reception from flight controllers. Works with FPV receivers and WiFi routers. Compact length is convenient for portable devices. Low VSWR minimizes signal loss.
