A little less analogue, and a lot more crap.

Nothing wrong if the panels are aligned correctly.

Perhaps the owner is having trouble getting a feedhorn that is correct for the reflector (Looks like a 1244 so a 0.8 f/d plus clamping arrangement).

That looks like an Alps narrow LNB, I would guess that any LNB with a wider feed would work better. The aspect ration of the photo seems to have been stretched.

I have attached a few pictures below of the correct Ku-Band feed that is matched to a Prodelin 1244 dish.
You can use the matched feed with an original Ku-Band OMT or it can be slightly modified to accept a C120 flange LNB.

Most likely it is Black Inverto Multiconnect. I think that simple Inverto Black Ultra (IBU) will work fine on this dish, if installed properly.
