Rf switch?

Question

why do u need an rf switch???

Answer 1

To switch between antennas, usually.  If you encountered this in your satellite system, it switches between the amplifiers in the center of the dish.  Each amplifier is looking at a separate satellite.  This allows the receiver to select a particular channel on a particular satellite.

I hope this helps.

Answer 2

using your PS2 and the RF switch allows you to connect the PS2 to the TV and have it connected to the cable tv. When you want to play the PS, you slide the switch to the PS2 and when you are done, you slide it to TV and remove the need to plug in the PS2 and then unplug it and reconnect the cable.
