Today's Octa LNB's are called universal LNB. This means
you are the low and high band can receive. This allows
You with analog and digital receivers are used.
Examples:
Qcto LNB plants are usually larger detached houeses used
because usually 84 connecting possibilities totally insufficient.
But it is better to the solution with external multi switch to use.
but more expensice!
It is also possible herewith a similar facility just replace
