The HOD12DP Hi-Gain Outdoor Dual-Band 12dBi Directional Antenna Kit is a heavy-duty, weatherproof antenna for extending the range of your 802.11 a/b/g/n Wi-Fi devices. The HOD12DP increases the wireless strength from a standard 2dBi (decibels) to a staggering 12dBi, resulting in a 400% increase in the wireless coverage and strength. The 2.4GHz is the most commonly used wireless bandwidth. It also has limited number of bandwitch channels for multiple activities, such as sending emails, video chatting, streaming movies, gaming, etc. In addition, the same 2.4GHz frequency is also shared between different devices such as laptops, tablets, and other common household devices such as microwaves and cordless phones. This causes interference and major backlog with your online activities. The Dual-Band Technology provide maximum flexibility for your Dual-Band compatible devices to connect to the popular 2.4GHz frequency and also off-load traffic to a faster, less-crowded 5.0GHz frequency. While the 5.0GHz runs at a high throughput rate, its wireless strength is limited. The HOD12DP strengthens and extends Dual-Band signal for long range, high traffic wireless networks. The Directional Antenna concentrates the signal in one direction for stronger signal and better long range wireless connections. The Directional Antenna is ideal for long range Point-to-Point wireless applications. Use a pair of Directional Antennas, one on each end for optimal results.
