Hi-Gain Antenna Technology Extends Wireless Range Hawking Technologies' HWC54D Wireless-G Cardbus PC Card Adapter features the latest in wireless technology. Standard wireless cardbus cards use low power antennas that deliver a circular signal pattern. This type of pattern recieves interference from the metal components within the laptop resulting in a drop in wireless performance and distance. The HWC54D solves this problem with its advanced directional 6 dBi Hi-Gain Antenna that delivers a strong concentrated signal in the direction of the wireless access point to establish a strong wireless link resulting in a significant increase in operating distance (Up to 200%). The Hi-Gain antenna position swivels and folds to make finding an optimal signal easy and simple. When you are not using the card, simply fold the antenna down for compact, safe, easy transport.
