[QUOTE="william-1, post: 880033, member: 193781"] I have found the same problem with some tuners & Lnb's,:( The Black Ultra has bad cross-polarity ratio with some frequencies above 12.500 when used with some highly sensitive tuners some transponders on 19.2 east even here in the UK show no signals 12722 H 22000, So I changed to the 0.3 MTI Blue line & all transponders ok on all tuners @ 19.2 east with my 100cm set up but not so good on weak satellites, With another set up on a 88cm dish the signals are ok with the Inverto Black Ultra with some tuners, So I imported the MTI 0.2 High line from Germany & got the same results as with the Black Ultra on some satellites due to the poor cross-polarity ratio some transponders = no signals on the 100cm set up.:( Having red through this thread I will now test a few more lnb's over the next couple of months in an attempt to find a good low noise Lnb with a good cross-polarity ratio.:) [/QUOTE]
