End of this is very important. Reflect the sound back

I'm thinking of trying to put a handle on the back of an old satellite dish.

TL;DW:

Nice thing is for sound you don't need strong material you could get away with kind of cheap corrugated plastic that outdoor sale signs are made of maybe even some good posterboard

riot shields that curve outward are commonly referred to as "capture" riot shields
