Description of Wifi Antenna:
Cable length: 16cm
Extended range 3BI Adjustable WiFi Antenna with gold plated U.FL to Female SMA connection cable. If you are looking for extended WiFi range from your ESP8266, CC3000 or other WiFi based projects then this Antenna package is what you need.
If you have a U.FL connector (the ity bity one) then use the cable, else the next most popular is the full size SMA connector in which case the 3DBI Antenna will screw on directly.
