Encore Wireless Antenna Booster enhances the out-going signal and reception sensitivity of 2.4GHz wireless devices, such as 802.11b/g/n devices. This omni-directional antenna complements WLAN (wireless local area network) for increased coverage. Replace your wireless adapter, router, or access point antennas with the ENAT-SO4 and you'll instantly improve your wireless connectivity at areas which previously had poor quality, such as behind a wall or beyond the maximum distance specified by the manufacturer. Install ENAT-SO4 with a snap. It doesn't require additional wiring or configuration. At the same time, ENAT-SO4 reduces the need to purchase additional access points or repeaters.
