 Hi, I'm part of an amateur radio astronomy group trying to get a dish on
 top of a roof to work.  We have much of the equipment, but are having
 trouble putting it together, as far as how exactly to hook everything
 up. Would this be the right newsgroup to post to? Thanks.

Ther are  a lot of interesting links  there to other Amateur Radio Astronomy
sites. You will probably find plenty ot keep you busy there 
Remember Google is you friend
