I had a thought the other day about what to do with the 2 old 60cm sky analogue dishes in my shed. I wondered if it was possible to point them both at the same satellite and combine the signal.
By my calculations, two 60cm dishes have approximately the same area as one 85cm dish. They would have to be very carefully positioned though because the wavelength at 12GHz is about 2cm, so if they were even 1cm out of phase, the signals would cancel each other out.
If the theory is sound then it could be extended. An array of 12 old sky dishes would cost about 60quid and have about the same area as a single 2 metre dish costing many times more. Although some sort of extra power supply would be needed because I don't think a standard receiver could power that many LNBs.
I am only theorizing here with no intention of trying this out, but what do you guys think? How difficult would it be to make this work.
