This morning, In Potenza (Southern Italy), with a Prodelin prime focus dish 11Ft (3.34 m) I am able to receive all satellites at 28E. Starting from the best position for Astra2F (11023 H, 8,8 dB ) I had to route the dish towards West to catch the maximum signal at 12480V . Doing so I passed the best position for Astra1N, The variation for 12480V was from 9.5 dB (position Astra2F) and 10.2 dB (Astra1N) to 13.0 dB (best position for 1240V). So I can affirm that 12480V is not on either Astra2F or Astra1N.
