Two-Antenna Kit for 2.4G Projects
This kit supplies two 3 dBi gain antennas and two U.FL-to-SMA cables for 2.4 GHz wireless modules. Each antenna measures 10.8 cm and each cable is 14 cm long. The gold-plated connectors suit hobbyist and prototype builds that need a quick range improvement.
Makers with U.FL or SMA Ports
Builders whose ESP8266, ESP32 or CC3000 boards expose a U.FL jack can plug the cable directly; boards with an SMA jack accept the antenna alone. Projects that require 5 GHz operation, higher gain than 3 dBi, or weatherproof outdoor mounting will not be served by this kit.
Steady Signal in Fixed Installations
The short 14 cm cables keep insertion loss low so the 3 dBi gain is maintained during continuous data streams. Fixed indoor nodes such as sensor loggers or home-automation relays see stable link quality without the fluctuation common with longer, lossy pigtail cables.

Questions about this item
Does my development board need a U.FL connector to use the included cables?
Yes, the U.FL to Female SMA cables connect to a U.FL jack on boards such as an ESP8266 or ESP32 module; the antenna then screws onto the cable's SMA end.
Can I attach the 3dBi antennas directly to an RP-SMA port on older equipment?
The antennas have a standard SMA male thread, so they will not mate with an RP-SMA jack; a gender-changing adapter would be required for that interface.
How do I verify the antennas are improving signal after installation?
Compare the received signal strength indicator (RSSI) values in your ESP8266 or ESP32 serial monitor before and after fitting the antennas; a higher (less negative) dBm reading confirms gain.
