I think the description is incomplete. The Ku spot beam aerial must be steerable too. Anything else wouldn't make any sense. It would be like fitting a spotlight to a fire truck and needing to orientate the whole vehicle to get the light pointing where you need it. In the case of a satellite spot beams, aerials that move independently of the satellite body are essential if the craft is going to be diverse enough to cover multiple or evolving missions over a 15 year period.Pietclock said:those three 2.6m dishes are clear, one is RX, one is for the spot beam and one is for the two pan-European beams (different illumination patterns I guess).
The steerable is a bit mysterous. Actually it is too small for a Ku Band Spotbeam, you dont get the gain. So my first guess was it is for Ka Band which isnt mentioned at all in officiall documents.
are you getting any signal from 2D now in tel aviv?solly said:if it final of spot beam need very large dish get mideast
Thanks solly.I guess Astra 1N UK beam tests are about the same strength as 2D in your area?solly said:dvbfilm
astra 2d too weak to get in tel aviv
need minium 5.5m go pick siganl not full transponder

There are going to be a whole new set of challenges to redefine the Fringes and cope with them.
Pietclock said:yes I think, while 1N might still be "mercyful" on us fringers, this most probably will change after that...
park_gate said:Yes but 2E, 2F and 2G are a similar design to 1N hence all the interest in 1N as it gives a taste of things to come.
I believe one of the differences is 2E, 2F and 2G will have a steerable dish for internet data for either Africa or the middle east. I don't believe 1N has this.
What's the reception of 1N like in Spain, how does it compare with 2D?
