Unfortunatley No, dish is on front wall, wires come in and straight to box or tv. nothing else in between. Anyway, explains the mystery of the LNB, maybe Landlord did, but its a Housing Association and i dont see how theyd get away with doing that in all honesty, maybe someone else did it, another tenant, not that hard to whip over an LNB swap, few minutes. Raging. Either way no use, means ive 2 redundant Wideband LNBs sat in my toolbox now ha ha, maybe somebody will need one.I'd guess that is from last year, but if you didn't twig it had been replaced then another tenant ( or the landlord ) has approved the upgrade without telling everybody.
There might be a converter sitting somewhere you have not looked, you could have your cables connected to the converted frequency ports if one is within the property.
