Hi guys, It appears that future satelllite operations are likely to require operations on multiple microwave bands. Has anyone looked into the design and construction of dichroic plates suitable for amateur band operations? Mode S/X on P3E comes to mind as one place that might need them? For me the mechanical aspects do not present problems. Design does present problems as I do not have the test equipment for ¨cut and try¨ :-( . There are references on descanso.jpl.nasa.gov .
