Connect up to four satellite receivers and dishes in your home simply and cleanly by connecting them all to the Digiwave 4-in 4-out Multiswitch in grey. This switch works with several combinations of dishes and receivers. If you have a dish with a dual LNB, you can connect the 2 outputs of your dual LNB to the 2LNB inputs of the 4x4 Satellite Multiswitch. Or connect 4 receivers and one dish to the Multiswitch and watch several programs and channels at the same time.
