Can an "Inverto" LNB be an alternative to a bigger dish ?

[Newb_Dxer]

I mean since we have less space for a bigger dish can we use an inverto LNB and can we get a similar performance like a bigger dish ?

I know a bigger dish is neccessary for Multi LNB setting but I am talking about a single inverto LNB on a Ku dish.

Is any one using this type of LNB ?If so please share your experience
