easy handling cheap price existing satellite system readjusted (years ago by the local e-fachhandel expertly installed) and lo and behold - better picture, because the bowl was just a bit of "adjusted".
due to previous recessions, I was warned because of the volume and taped in advance already a piece of tape over the "Speaker Out". which was perfect (that's why I have not tried it without tape and can not comment on that)
