The Hawking Hi-Gain 12 dBi Wi-Fi Directional Window Antenna offers a convenient solution for strengthening and directing WiFi connection signals. The power rating of WiFi antennas is measured in terms of decibels (dBi). The HA12W Window Antenna boosts the antenna power of standard antennas from a minimal 2 dBi to a more potent 12 dBi. It is an easy to install solution that plugs directly into an antenna port of your wireless device. The HA12W is built with high grade materials, ensuring maximum quality and performance while still increasing your coverage by about 300% over standard antennas. An innovative swiveling window mount allows you to aim your antenna directly towards areas lacking WiFi signal coverage. Whether extending the wireless network from one corporate building to another, or simply from the front house to the back house, the Directional Window Antenna provides wireless users with a high powered solution to extend their wireless network.
