Summary: I was skeptical of this item because of the inflated claims ("strongest on the market") but I was pleasantly surprised when I hooked it up and saw significant signal increases on every wireless network in the vicinity.
Summary: This adaptor solves the many problems inherent in wireless cards. Sure, they make high power wireless cards, but the strongest only go up to 300mw. The antenna connections are so weak on the wireless cards, they tend to break off and become useless in just a few days.
Best WiFi antenna on the market but better with the 7dBi panel antenna
2 September 2014
Summary: Nearly all Amazon.com reviewers agree, the Alfa AWUS036H is the long range WiFi antenna on the market. But with 3 antenna options to chose from, which is the best setup? I own the all 3 wi-fi antennas from Alpha: 5dBi omni-directional, 7dBi panel, 9dBi omni-directional.
Summary: works flawlessly under backtrack and kali,as well as mac or PC os's. Works fantastically and I wish I would not have waited my money on anything else. Don't waste yours as well, get the ALFA and take my word, its a beast!!
