This is a 9 dBi gain rubber duck antenna for use with wireless adapters that have an RP-SMA connector on them. This adapter is made by ALFA Networks and has the ALFA  logo on the product. Many PCI and some USB adapters have this type of connector. ALFA models AWUS036H, AWUS036NH, AWUS051NH, and AWUS036NEH are all compatible with this antenna, as is any other Wi-Fi adapter with an RP-SMA connector.

This measures 15" in height. It is heavy, so some wireless USB adapters, including the ALFA unit mentioned above, may need to be mounted or leaned against something in such a manner to prevent the setup from tipping over.

This antenna has no electronic parts and requires no installation on the computer- simply attach it to the RP-SMA connector on your wireless adapter and it will automatically work. This may seem basic, but just to be clear not all wireless adapters have an external antenna connector. You should only buy this if you know your adapter has an RP-SMA connector. If you are unsure, please email us with your adapter brand and model number.

State sales tax of 7% will be added to FLORIDA purchases only. There is no sales tax for any other state.
