This rubber duck antenna Wifi 2.4GHz is ground plane independent, meaning it does not need to be connected to the ground-plane of a device to radiate efficiently. On the other hand, neither is it seriously detuned by connecting to a ground plane, thus avoiding a problem notorious to smaller antennas.

It comes with an SMA(M) connector and swivel mechanism that allows the antenna to be rotated to fit in tight environments. The 90° hinge structure has been improved and strengthened so that the antenna in a 90° position would not drop down if used in environments prone to vibration.

The Rubber Duck antenna series are weatherproof and waterproof high gain antennas that provide an excellent choice for outdoor and indoor use, provide a wide coverage with an omnidirectional pattern installation and can be mounted on the outside of a housing. Our rubber duck antenna is omnidirectional "rubber duck" antenna, flexible "rubber duck" antenna, compact and easy to store, with the choice of MMCX, RPMMCX, RPSMA, RPTNC and other custom plugs, we also offer a variety of options customized solutions for the external wireless antenna, connectors, pigtail, and mounting bracket.
