I just bought a newly built home, and it comes prewired with RG6, and they have a "satellite box" on the outside of the house where you can mount your dish, and run your wires directly in...so basically I don't have to drill any new holes or anything according to the builder. My question is, what do I need to know about doing an installation this way? I plan on eventually buying the 921 and Superdish, and thus having the installer put that stuff in, but in the meantime, I will be doing my own installation probably. I haven't had a chance to look at the "box" up close yet, but I was looking to see if anyone else had experience or advice on doing this type of install. For now I basically want to run 3 receivers in the house...But may want to increase that to 4 in the future. Thanks.
