Dual Band 2.4GHz / 5.8GHz 3dBi Wi-Fi Antenna - SMA Male

This dual band 2.4GHz and 5.8GHz Wi-Fi antenna is a compact 3dBi omnidirectional antenna with an SMA male connector. Its coaxial design radiates evenly all the way around the antenna, so it suits routers, access points and wireless dev boards that need to reach devices spread around a room rather than in one direction.

The hinged base lets you mount it straight, at a right angle, or anywhere in between, so it can stand upright even when the connector comes out the side of an enclosure.

Note: This antenna has a standard SMA male connector (nut with a centre pin). Many consumer routers and access points, including D-Link and Linksys models, use RP-SMA instead, which this antenna will not mate with properly. Check your device's connector before ordering. For boards with an IPEX/U.FL connector, such as the ESP32 DevKitC 32U USB-C, add a U.FL to SMA female adapter cable, or get the dual band antenna with the adapter cable included.
