Wireless N Desktop Card directional
Hello,Is there a wireless adapter with an antenna that can be mounted outside
In case you're still interested...
If you don't find an (internal/card) adapter with cable and antenna, you might consider purchasing a Wireless N USB device, and incorporating it in a homemade directional antenna (for example: http://www.usbwifi.orconhosting.net.nz)
You could also purchase an internal card with external antenna connector, then buy a cable and buy or build an antenna.
With Coax [antenna] cable, keep distances short for less signal-loss.
Of course, with outdoor antenna, lightning protection should be considered.
