I recently purchased a directv international dish 36" elliptical with both KU and C LNB. I have been trying to catch G25 97.0W but have been unsuccessful so far. Is there something particular about the LNB used for this dish that would limit its usage on other sattelites? Thanks for any help you guys can throw my way. The channels I am interested in getting is actually on the KU band and not C band but I haven't been able to raise a flicker on either one.
