  • Page 4 2. Introduction 2.1 Description This high-gain directional antenna is used with Black Box Pro Series Wireless Ethernet adapters. Use it with the LW0055A, LW0056A, LW0057A, LW0058A, or LW0059A for outdoor applications in which higher gain and larger distances between sites are required. It has a narrow beamwidth of 6°, which increases the sensitivity to alignment inaccuracy, but decreases the fading caused by multipath propagation.
