[QUOTE="Channel Hopper, post: 2779, member: 175144"] Im not sure if anyone remembers the saga of the old analogue Astra satellite and the sudden loss of channels in the South of Spain three years ago All the Astra footprints are planned in advance ofthe launch and this is probably what you see on the printouts from SES. However the antennas / TWTA systems on the satellite are steerable from the ground and if deemed necessary to bring some change to the footprint, this can be done in about a day from Luxembourg. If Sky puts enough pressure onto SES to remove a territory that it knows is receiving the signal on a standard size antennathen the beam will be moved and the signal compensated for in the other regions Additionally the fall off of signal from the higher frequency satellites is much sharper than the older analogue frequencies so a small change in direction could make a lot of difference to the marginal areas listed [/QUOTE]
