Siretta 2.4GHz WiFi Stubby Antenna with SMA Plug, 3dBi
Compact Siretta 2.4GHz stubby WiFi antenna with SMA plug. 3dBi gain, omni-directional, for modules, routers & portable equipment.
Enhance the wireless performance of your portable equipment with the Siretta 2.4GHz WiFi Stubby Antenna. Designed for a secure, direct connection, this omni-directional antenna features a rugged, flexible whip construction protected by a durable rubber overmould. Its compact, low-profile 'stubby' design is perfect for space-constrained applications without sacrificing signal strength.
The antenna utilises a 1/4 wave radiating element and is terminated with a standard SMA male plug connector for reliable integration with a wide array of popular Wi-Fi modules, routers, access points, and IoT devices. With a gain of 3dBi and a low Voltage Standing Wave Ratio (VSWR) of 1.5, it ensures efficient signal transmission and reception across the 2.4GHz frequency band, which is essential for stable Wi-Fi and WLAN connectivity.
