It's impossible to have 36-39/40-42E on single dish, since distance between LNBs is too small. Only 36+42 is possible, and LNBs are placed next to each other in such case. Also, for proper reception of 40E, sizes 1m and bigger are needed, 1.5m for weather independent reception at least.
Regarding 39E, have no info, since nothing interesting there, almost never tried that sat, but can try on 1m motor if you wish.
