that lnbf has built in switch, you wont need another one.
one RG-6 cable from your DVB receiver will do, along with the
actuator signal and power wires.
But - if you are running a new cable, please do pull 2nd RG6 at same time.
If you do end up with a DC-II 4dtv receiver, you'll need separate Ku and
C band cables.
