The HAI6SDA Indoor Directional Antenna boosts your IEEE 802.11b or IEEE 802.11g wireless signal strength from 2dBi (Standard) to 6dBi! One of the major problems with many wireless networks is the poor coverage area of standard access points and wireless routers. Hawking solves this problem with a hi-gain external antenna that attaches directly to the connector of your Wireless Access Point or Wireles Network Adapter. The Indoor Directional Antenna amplifies your wireless signal in a concentrated direction, giving you a very strong directed signal. The HAI6SDP/HAI6SDA is effective on both wireless network adapters and access points. When combined with two directional antennas directed toward each other, your wireless range may be extedned up to 2750ft. Installation is simple. Hawking Hi-Gain Wireless antennas are designed to work with most Wireless Access Points, Wireless Routers and Wireless Network Adapters. By using the popular Reverse-SMA connector, the Hawking Hi-Gain Antennas can be used on most Wireless Devices. Jumper cables are included for greater compatibility. Simply unscrew your current antenna and screw on Hawking's Hi-Gain Antenna and you're ready to go!
