[QUOTE="PaulR, post: 802962, member: 176256"] You're not the only one who has daydreamed on combining several small dishes but at the moment the consensus is that it is still beyond the amateur's reach. As I understand it the outputs from multiple arrays are stored and then combined using powerful computers so it's not real time. They use highly a precise (atomic?) clock to make sure that all the inputs are in phase and then I suspect that a lot of statistical manipulation of the data goes on. Musing on use for amateurs you would need the oscillators in all the LNBs to be completely stable and in phase in order for the IF outputs to be in phase. You would then need millimetre accurate co-axial cable lengths before combining the signals. I'd love to be proved wrong on this BTW! [/QUOTE]
