Thanks. Appreciate the reply. From a brief look that might detect 2.4ghz too?

Really wish I was clever enough to do electronics!

Depends on the length of the antenna. I'd bet you can get a length close enough to be a quarter-wave 5Ghz and 1/2-wave 2.4ghz antenna. Just buy a 2.4/5Ghz combo antenna and slap the diodes across it.

    I love simple solution like this. It'd be cool just wandering around being able to detect mobile and stuff with a tiny led.

    This sort of thing is definitely why I come the HN.
