I recently upgraded to the h-20 receiver and slimline dish and was wondering how many of you subs leave the "b band converter module" connected. Does this module affect the picture quality? I know the installer said the signal strength is impacted but not the picture quality. Is this true? I am receiving some 1080i channels and they look nice to my eyes but was wondering if I remove the module will the picture improve? My apoligies if this is a repost. Thanks in advance!
