Hi,
your request is rather vauge. you have to be spaecific whether C band etc, -- finally, the cost and performance of a home made Rx is questionable unless you go for a prefabricated KIT where other things are taken care by the kit supplier and you are likely to get some satisfaction. now a days with all digital satelyte broadcasting and with code locking -- you may have to redefine your project to make it more practicable.
All the best

Buy one!, there's no way you could build one for anywhere near the cost, even assuming you could buy the specialised parts, and make the multi-layer PCB required.

You will be hard pressed to find any. They are all under NDAs, the MPIAA and cable industry are paranoid that the public will get the info and get free cable.

Ever hear of Free To Air satellite?
