USE PROMO CODE 15DISCNT
this one does not have the carrying case and sells for $37.99 so i guess
this is a good deal

The Alfa AWUS036H is the latest version of the most powerful card available.
This has a stunning 1000mW output power. So if you are looking for a device
to connect to an outdoor 2.4 GHz antenna, such as on a boat or an RV, this
is a perfect solution. It outperforms wireless cards th... 阅读全帖

I found some Alfa that have a $5.00 off Promo code - it took me while to put
this list together and I could have overlooked some listings, please let me
know if I missed anything and I will update this page.
This is NOT a FLAMING deal but for anyone interested in buying Alfa's now is
good time. They had the AWUS036H on 1saleaday yesterday for $19.99 shipped,
but for whoever missed that the price is pretty decent, and you can now buy
them in bundles with a longer antenna. There are some other mod... 阅读全帖

土,到处都有卖的。

然后装backtrack和aircrack。国内的软件大多是基于BT的。

玩过500mw的usb wifi,加上7dbi超长天线,没觉得比我dell 笔记本内置的网卡好多少
我用得就是这个
http://cgi.ebay.com/ALFA-500mW-USB-High-Gain-WiFi-Wireless-G-LAN-Adapter_W0QQitemZ120458839619QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item1c0be80643&_trksid=p3286.c0.m14
但从软件看信号强度,是比内置的强许多,但实际上如果内置的卡无法正常连接的信号
,号称500mw外置的也不能稳定接收。
室内的最高9dbi的天线帮助并不大,除非搞室外天线,弄个小锅挂出去,不过太麻烦了。

无线路由信号不好,打算换条9dBi天线(在mwave上$4.5)。这样高增益的天线会不会
对身体不好?还见到有个无线网卡5dBi,功率300mA-500mA的,这样的功率算不算大?以
前听说那些大功率的蹭网卡对身体不好。

9dbi 应该还好
手机应该也有5个dbi以上吧

相对无线路由原配的小天线(2dBi)来说,9dBi算高了吧.

先声明:俺电子信号知识完全是门外汉。俺的路由器是asus rt-n16.
看到这里有个有趣的专门给rt-n16的天线组合:
http://store.sputnik.com/3-antenna-kit
推荐三个天线一个5.5dbi,一个7dbi,一个9dbi
根据俺网络google的结果,似乎天线dbi高,覆盖距离是提高了,但覆盖角度却变小了。看下图:
请懂行的兄弟赐教!谢谢
