These SignalMax amplified multiswitches are used where multiple satellite decoders are connected from a single satellite dish. A typical installation would comprise of a TWIN OUTPUT LNB installed on the dish with twin cables connected from the LNB ports to the vertical and horizontal input ports of the multiswitch. From the switch, a single cable is run to each satellite decoder. In the case of a pay TV decoder such as MyStar or Foxtel IQ, two cables are required to be connected to each decoder from the switch. A 2 in 8 out multiswitch is sufficient for up to 8 single tuner decoders or up to 4 twin tuner decoders - you can of course mix them. These switches were Austar approved until the Foxtel take over thus the quality and reliability is paramount. Being amplified, these switches provide a no loss connection from the dish direct to the decoder unlike a non amplified switch. Can be mounted inside the roofspace.
