I thought as much. Actually, I have quattro LNB's and I feed the
whole house via the multiswitch. Quattros with their fixed outputs
served by the switch alone was the most scalable solution I could
find. Unfortunately, each room is provided with just one cable.

For now, I grabbed a second cable from the next room, where it's
unused, so all's well and I'm happy again. :)

Thank you,
