This is the antenna that increases your home computer network's wireless speed and reliability in areas of weak signal strength. Its patented, spatially-diverse design is optimized to receive signals in all polarizations--a spherical signal pattern--capturing weak signals that lesser antennas drop, resulting in better reception, especially beneficial for streaming video. It attaches to an existing wireless router (not included), replacing an existing antenna without the need for software installation or reconfiguration. Its flexible gooseneck positions the antenna in an upright position for optimal signal reception. Compatible with 802.11b, g, and n 2.4GHz wireless routers that have removable external antennas.
