John F you have not mentioned why you are looking for splitters nor what system you are looking into? most of the posts here reference the OTA (antenna) and cable TV wiring systems/configurations. As stated on these systems the splitters are located in the wall or ceiling near the antenna booster plate, remove the plate and reach in behind it, The satellite system wiring is a complete separate configuration and those splitters if any could be virtually anywhere in the walls or ceilings. Have you found the booster if you are chasing down the splitters in either the OTA or cable TV system
