[Antennas] Passive reflectors

Many years ago when I was in the business of designing microwave links,
a major supplier of passive relfectors was an outfit named Microflect.
They had an engineering manual that included all sorts of detail on
designing links using passive reflectors -- just the sort of thing
you're asking about -- but I have no idea where my copy went after all
this time.
Microflect has no presence on the web by that name, but a Google search
on "Microflect" showed an outfit named Valmont/Microflect with that sort
of product line, indicating the company had been swallowed up. The
Valmont site didn't appear to have any engineering data.
Google also found an article by Ray Thrower, whom I knew when he was
working for Microflect, at:
http://www19.addr.com/~longline/places-routes/Thurmont_repeater/EW0569-fc.html
Suggest you follow the Google route using "Microflect" as a target. If
that fails, try "passive repeaters". You'll probably find the info you
need.
