[QUOTE="davemurgtroyd, post: 1002424, member: 319227"] Note I said "optimal" performance. I assume (have not actually measured it) that monoblecs are designed witha slight "toe in" of the wave guides - appropriate for the dish size and satellite separation). By "toe in" I mean that the centres of the wave guides are closer together at the nearest point to the dish than at the farthest on fixed separation monoblocs. Obviously this toe in is set for a particular dish size and separation. I believe the "signal acceptance angle" of these waveguides will allow their use on the "incorrect" size dishes. From memory of my adjustable the body of the lnb that they slide apart on is not prefectly straight but slightly curved to increase this "toe in" with increased separation. [/QUOTE]
