[QUOTE="william-1, post: 909898, member: 193781"] Even with juggling the frequencies 2C will be of little use @ 28.2/28.5 east as it cannot cover 11.2 to 11.7 GHz only the combination of 2F,2E & 2G will this part of the Ku band be covered when Eutelsat 28A moves from this orbital position, 2A is a bit easier to cover 11.7 to 12.5 GHz as 2E & 2F can duplicate these frequencies, 2C could cover 11.7 to 12.2 GHz also but with the bigger footprint most of the transmissions may be encrypted 10.7 to 11.2 cannot be used on 2C as the footprint is too large. With hind sight the latest Astra satellites should have been able to cover the whole Ku band 10.7 to 12.75 as the Eutelsat 13B,13C & 13D satellites can, I suppose it was cheaper to make the satellites 2E,2F & 2G the way they did but it did not take into account that with the takeover of the whole Ku band spectrum by SES that they would be deficient in some parts of the Ku band @ 28.5 east :( [/QUOTE]
