There are 8 Quad LNBs for fixed reception of 8 satellites (7 on old toroidal dish, 1 on 75cm Cassegrain type FUBA dish).

I'm curious, I'm not sure where Riga is located but you are talking about a 30 inch dish (75cm) right? Where I am, Ku requires at least 39 inches which is closer to 100cm before we can receive Ku signals. Thanks in advance.
