Greetings to all:
The first thing i should do, is appologize to Mr. Cole for addressing
him as Cole<err>.
As for the PrimeStar dish, it's made with a stainless steel grid inlaid
inside the fiberglas covering(my 1.2M dish has a .22 cal. bullet hole in
it that shows this very nicely!).
The stainless "grid" appears to be about a "40 mesh", which should work
well up into 5 Ghz.
I suppose the dish had to have an internal reflective layer due to the
absorptive properties of the fiberglas, but it will also add ridgidity
to the dish in a windy environment as well.
Sorry Mr. Cole for the mistake }}:-( !
73!
