I ran a BSC-621-2 on an offset 4 foot dish, along with 30" ku dish and Universal LNBF, and an old dish network dish for music.
There was
HH120 motor on the 4 foot dish.
It all ran to 4 port
Diseqc switch.
Port 1 =
C band 4 foot
Port 2 = Ku band 4 foot
Port 3 = Ku band 30" dish fixed at G10R
Port 4 = Ku band 18" dish fixed at Echo8
I had to turn 22khz on for the Universal LNBF's.
It worked just fine. No need for 0/22khz switch.
