Hello I put together an S band system for a friend. He changed his mind, tried to sell it at a flea market, no go. I will try this list before ebay. It is a 24x19 inch dish, 5 1/2 turn helix feed, 3731aa downconverter with power supply, and mounting brackets to fit over elevation rotor. Pictures and more details upon request. 73 Bob W7LRD Seattle
