Re: Cheap, Makeshift Parabolic Dishes?

 

Do the dimensions matter? i'm seeing a lot of shapes and sizes... are there simple rules-of-thumb that people use?

Hey all -

I'm curious if people here have any recommendations for cheap, makeshift parabolic reflectors? I'd like to experiment a bit with the idea, but I'm hesitant to spend $80 on some meticulously curved glass. Are there any interesting alternatives?

Thanks!
