2.4 GHz Omni Antennas
2.4 GHz Omnidirectional WiFi Antennas: WiFi Omni antennas are constructed to cover / illuminiate a large area with a wifi signal. They are very well suited for use on a WiFi base station (such as a WiFi router, access point etc.).
In principal: The higher gain of the antenna (declared in dBi), the higher the range of it.
