This is not just an antenna. (it has no external RF, antenna cable, is the proof)
It really is , full Wifi network card (nic) with an extremely high gain antenna. (nice idea that)
Once enabled (no Apple MAC support or MFG site pages for same, found) it works great, from extreme distances.
(i have built many of these from scratch, so know the ropes)
Imagine a powerful directive Radar dish. It is very directive, such that bumping it , you might lose the signals.
How ever if near your home (say) and is 300 feet from your router. (wifi) you will pick it up , very well.
You must disable you existing wifi port in your laptop. (and switch ports)
Then, install the comes with CD drivers (may need them, W7 may find them via MS update , as always)
You next ,need to find this new USB wifi port antenna (best name) in the device manager.
Then in wifi connections in the control panel ,enable this new antenna and point it at your far source of wifi.
now the unknown!
the MFG. fails to state what security modes work, nor what chip they used, making this important factor , unknown.
That means, what?
if, say you are running WPA2 full encryption on your router, it might not work.
It may not fully support "N" level routing, or 5ghz band. etc, etc...
How ever, some routers have a side Guest port , that may work with this device.
One thing that does work, is connecting to the open adhoc hotpot cafe down the street,. just use bean bags to hold the base steady.
