[. . . ] OBTAINING OPTIMAL ANTENNA PERFORMANCE Obtaining one antenna or two antennas?Depending on your wireless application, you may need two antennas, one on each end to optimize the signal. If you have an Access Point in a small environment, i. e. home, with multiple users in differents locations, it is more cost effective for you to use one Omni-Directional Antenna. However, in areas that recieve poor coverage, you may need a Directional Antenna to amplify the signal from the receiving end, i. e. For extended wireless range, it is reconmended that you use two Directional Antennas facing each other. If only one Hi-Gain Antenna applies to one end and a normal (manufacture standard) antenna on the other end, the result may not be as great as using two antennas. The Hi-Gain side may send out a signal quickly, however, the other end (manufacture standard side), may not have the strength to send back the signal instantaneoulsy.

OBTAINING OPTIMAL ANTENNA PERFORMANCE (Con'd) HA12W: Hi-Gain 12dBi Directional Window Antenna Up to 5, 000 ft To obtain optimal distances, the two antennas must be directly facing one another with little or no obstructions interfering with the signal (if possible a clear sight from one end to another. NOTE: Many factors in the environment may affect your wireless range. Different wireless devices may have stronger signals than others which may derive varying performance results. For example, the wireless output power on Access Points may vary from one brand to the next, which would create different results. These published results were obtained using HAWKING TECHNOLOGY wireless devices that are tested to obtain the highest performances with HAWKING TECHNOLOGY Hi-Gain Antennas. Caution: This equipment complies with FCC radiation exposure set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 1 foot during normal operation. -8- HOW DOES THE ANTENNA WORK?

Simply, take your wireless device, whether it be an Access Point, Bridge, Wireless PCI Card, USB Adapter etc. , and check to see if it has a removable antenna. To determine whether your original antenna is removable, examine the base of the antenna to see if it is a "screw on" type or a non-removable type. To remove your original antenna, hold it by its base and unscrew firmly by turning it counter-clockwise until the antenna is seperated from the connector. After it has been removed, take your Hawking Hi-Gain Antenna connector and screw it (clockwise) onto your wireless device. After you have firmly attached your Hi-Gain Antenna, place it in a location where it will achieve optimal performance. -9- HOW DOES THE ANTENNA WORK?
