Find the TV antena power panel for the external TV antenna (King jack). Remove the screws from the beauty plate. Pull the plate, wires and coax out of the hole. At the end of the short section of the coax is the splitter. The antenna power panel will be located up front usually on the right side of the coach near the entry door in a cabinet.

Once you find the splitter, you might as well replace it with a quality "gold" splitter. I found that made a difference in over all reception. On my 29.3 the splitter was located in the wall between the information/switch panel and the ant. power button. I relocated the splitter from between the wall so I could have easy accesss if needed.
