Hi there,
this is my first post here, hope not being off topic 
I was asking myself if there were resources over the net that cover the
development of a cassegrain antenna [from the design up to the building]
in a homebrew fashion.
Thank you for paying attention towards this mail
Bye bye

PS. I already posted this message to rec.radio.amateur.homebrew, but a
user suggested to me to post it here too.
Hello, and while I can't point you to any specific sources I would ask why
you feel you need to use a Cassegranian feed. This complicates the design
in that you need both a parabolic main dish and a hyperbolic reflector.
Have you worked out the antenna's frequency band and required radiation
pattern/gain? Would a non-Cassegrainian feed (e.g. placing the main
radiating/receiving element on a support at the focal point of the
reflector) be viable? Sincerely, and 73s from N4GGO,
