Kris, I am assuming you know your KingDome is NOT HD capable...so if you're trying to get good reception with that it's not going to happen. We are satisfied with SD and are happy with the clarity of the picture. That said, we also carry the 18" round for those situations where it's needed. I ran a separate cable to the wet bay into the overhead cabinet into a 4X4 multiplex switch. From there I sent the signal to two A/B switches and on to the two TVs. A = Kingdome and B = outside dish. This makes it easy to switch between the two. I have pictures somewhere. If you need/want them, I'll find them. We've had good reception with the 18" dish all through the country. I disassemble it when not in use and it takes up very little space...Dennis
