I thought that also. But when I looked, I have four RG cables that penetrate the floor. One is orange that goes to a separate connection which I presume is the satelitte connection. All of the others terminate at the splitter/booster. One is grey, which I presume goes to the bedroom, because when I pulled the mounting plate in the bedroom, the cable that is attached is grey. The other two, one black, and one kind of an off-white, enter/exit the penetration. One of them I presume the black one, comes from the cable connection, and the other one, the small off-white one, probably from the antenna itself.
