For best results!

The larger antenna works fine with my wireless PCI card "WN-551g". With the PCI card alone I had the unfavorable structure of my house very little reception because the wireless router is in another floor and through a few concrete walls "through spark" must. With the external antenna I have now instead of 1 or 2 strokes received full 5 strokes, so the device served its purpose and was also still have favorable.

However, the 1-meter long antenna cable in my opinion is a bit too short. If you want to attach it to a metallic surface, such as a pin board (magnetic base), you need a longer cable definitely.
