Has anyone ever designed a SW transmission system using curtain arrays
that
has a beamwidth of 2.5 to 5 degrees?
Most standard curtain arrays [HR 4/4/1 to 12/6/1] have 15 to 30 degrees of
beamwidth.

Talk about the curtain array... that brings to mind a somewhat recent class
I took, that of all students attending, there was the daughter of a VOA
engineer responsible for rebuilding a number of stations; she was in my
study group and what a nitwit!

I played dumb and never let on I knew anything about shortwave broadcast
stations or the pecuilar circumstances and delicate political situation
regarding one of her father's constructions.
