That setting is needed if you have a longer cabling, thinner wiring or loses at the connectors. Not really an issue. Just a setup that makes the DVB card to use a higher voltage when powering up the LNBf and switching the polarization, in order to compensate for cable loses. > > But the GOOD news is: yes now you made it!
