The TV antennae and satellite dish signals are both in different frequency
bands. The multi-switch is adding the two sets of signals together on one
line because they will not interfere with each other. To separate at the
receiver end, you need to use a signal splitter

. The TV input on the receiver will reject the satellite signal, and the
sat input will reject the TV signal.
