Since the wavelength for wifi is about 1.5 cm. It would be hard to make a
dish that small. Remember, the dish is not the antenna. It is a parabolic
reflector that concentrates the signal (just like those solar cigarette
lighters used to have a dish that focused the sun onto the end of
the cigarette). It does not have to be that heavy, it just has to be able
to reflect the signal onto the antenna.

Hey,
I have a question about dishes.
I have a primestar dish that I play around with for my wifi stuff, but it
is huge and heavy.
I have the big Trevor-Marshall-style one (

How small can you make a dish for 2.4 GHz before it is not worth it anymore?
Would a dish smaller than the wavelength be effective?
