Since you ask - there are no digital LNBs. They're all analog. The digital bit happens in the receiver, where the analog signal gets sampled (A/D'd), and converted into a string of bits, which is then interpreted as digital. The LNB doesn't know the difference.Second point.
I've have upgraded the sat system at home (parents) they have an 1.4 m prime dish antenna. The system was installed in 1991-1992, the LNB is an Sharp Carat but there are no papers anymore about it, antenna was pointed at Astra 19°E.(at that time the recommended size for Romania was about 1.6 - 2.0 m) .
Has anyone an idea what that LNB can do? IT has to be an analog one, I tried to open it but 4 screws are stuck and can't be moved without using excessive power.
That is a normal universal LNB. Throw it away, and buy new one - it's bound to be better.So here you have, on the feed horn the inner cylinder is missing, I forgot to put it back.
...But. The question then is: Is the dish a Prime Focus, or an offset one?[snip] ...they have an 1.4 m prime dish antenna.
(Ahem. Both dishes pictured have three arms...)No is no offset dish, has 3 arms :-)
Sorry, just wasn't clear of what you meant with a "prime dish".I know the differences mate (here is not that hard as in astronomy optics: frauenhofer, half-achromatic, apochromatic, schmidt-cassegrain, gregorian, schmidt-newton, newton etc)
You're funny people, all you need are pictures, so long you dont request nudes its fine for me
So here you have, on the feed horn the inner cylinder is missing, I forgot to put it back.
Your parents do seem to have a nice 1.2 or 1.4 metre PF dish.As I sad the system was installed in early 90´s and that's sure because I was there. And no, they don't have the papers anymore, we are speaking about something installed almost 30 years ago something that was working until Astra moved to digital transmission.
In autumn Ive changed the LNB and got a new LG TV with sat receiver build-in (that was my birthday present to my father). The LNB was changes after asking what I have to do to make the system work again and the answer was LNB+Receiver....
The only part that I have here is the LNB and I've asked my mother to take a picture of the dish.
