If you need some directionality (and more gain), get the AirView-EXT model and get one of these:

Mine came without the S/S mounting plate and I just velcroed the thing to the lid of the laptop (~4x2x1 in.). I also have
a higher gain omni that goes on the same velcro, so after you identify the interference, switch to the Sector ant. to get
the direction if needed.
