2.4ghz model is more Like $50 and works nearly as well as the wi-spy.

wi-spy DBx is stll about the cheapest I've seen for a 5ghz spectrum
analyzer, and is worth it for that alone but the interference problem
you're trying to nip in the bud is is likely in 2.4ghz anyway.

but it sure would be nice to have a general rf peek at the wifi ranges.
two weeks ago, in hk, we had rf interference that essentially killed the
wifi, but it did not show on wifi analyzer.

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.
