The times when a Netstumbler kit comes in handy are:

• Newbies.
  The first thing we all want to do when starting in the WiFi hobby is to look around for other networks. This goes by a many names, such as: Stumbling, WarDriving, and even WarFlying for those with a plane. The software of choice for this is the Netstumbler freeware. You can use your antenna of choice. Of course, the UltraUSB makes an excellent WiFi 'client' interface for a laptop when not in use for stumbling, and the antenna can be used later as part of a future wireless network.
• Antenna Pointing.
  For high gain directional antennas, where you can't simply point by eye, it is best to use Netstumbler to fine-tune the antenna pointing to get the maximum signal. Of course, the UltraUSB makes an excellent WiFi 'client' interface for a laptop when not in use for pointing.

This kit includes these parts:

	1 x UltraUSB interface with external antenna connector. Vista Note: The UltraUSB does not work with Netstumbler on Vista. But - that is not a problem if you want to measure signal levels and point antennas. Just use the Utility that automatically installs with the UltraUSB. The manufacturer's utility works fine on Vista and gives signal strength readings.
	1 x 3m rpSMA to Nmale, low-loss antenna cable
