Re: [amsat-bb] Re: AIDC 3733 3' BBQ Dish

["John / NS1Z" <ns1z@xxxxxxxx>]

I printed that section out but wanted confirmation since the dimensions of
the struts on an unmodified Channel Master 1.0m dish put the focal point out
an additional 4 inches (23.8" vs 28.6" which was calculated with D2/16d ).
Physical dimensions of the dish are 40" X 43" and the deepest point between
opposite edges is 3.5". On the rear it is marked Channel Master 1.0M.
