Signal strength meter for 802.11 wireless?

I'd like to have a signal strength meter to use when aiming high-gain
antennas for use with 2.4 GHz wireless network signals. This is similar in
function to the "satellite finder" tools that TV dish antenna installers use.

This would be just a raw antenna; 802.11 doesn't use amps at the antenna,
that I've ever seen.

I'd like to make it as simple as possible, either with a meter element alone,
or with an audible beat frequency to indicate maximum strength when aiming.

Sure a laptop with "stumbler" software will work, but putting my laptop at
risk (holding it in one hand while aiming with the other, on the roof, no
less), and the lame daylight performance if most tft displays makes looking
for an alternative very desirable.

Circuit suggestions?

Thanks,
