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

Not off topic at all. You may want to try the rec.radio.amateur.antenna
group.
