I am just about ready to try this service and I would really like to buy my own dish and do a self install. I had several FTA dishes about 15 years ago and am sure I could still do it. How much signal gain could I expect in comparing the dish Orby supplies in their self install kit, the Winegard 30 inch dish and the GeoSat Pro 36 inch dish. Obviously larger is going to be better but I would not wish to stretch the budget or the limit of my physical ability needlessly.
