A lot of us went into " detective mode " and scrounged our C band dishes . Look for a 10' dish . Or several . May need to take parts from more than one to get a working whole .
Here are some of the better links in my Satellite Shopping Favorites list
Mech Tech - http://mechtech.satforums.com/
If you don't see it on his site, email or call him. It's hard to beat his prices and service. His number one priority is customer satisfaction.
Global Communications - http://www.global-cm.net/
Good reliable source and competitive prices. Be sure to checkout the bargain area, espcially if you're interested in a HtoH mount for 8' mesh or 6' solid. Cool site to visit just to look at his dishes.
If you're into Satellite Radio Telescopes (SRT): Custom Astronomical Support Services, Inc. - http://www.cassicorp.com/
Additional SRT sites http://web.haystack.mit.edu/SRT/index.html Full documentation for building your own AZ/EL controller for those who want to scan more than the Clarke Belt
