"Switch has 12-volt DC receptacle, built-in two-way splitter for second TV outlet, a convenient power-on / off indicator light and cable TV input "
did you get tehj white switch with it?? if so sounds like it has an input for a 12v DC power supply. Put the power supply as close to your dish box as is practical and try it out. You can get a 12v DC power suplly at radio shack. The center pin on the power cord is almost always positive.....
