I have such an incredibly small line of sight, I cannot pick up local channels on my sat. Does anyone know if I can set up another dish to tune in the local channels satellite(I forgot which satellite that is), and then connect the two dishes through a multi-switch? Has anyone ever tried that? In theory it seems like it would work. I currently have a triple lnb oval dish and have access to another oval as well as an 18" round dish. I currently only have directv/tivo dual receiver hooked up. Any help would be greatly appreciated. Thanks.
