[QUOTE="Analoguesat, post: 1031626, member: 176362"] Eh??? Anyway Hotbird doesnt have spotbeams - the beams are ultra wide covering western Europe well over almost as far as India. Even if there were spotbeams it wouldnt matter as the important bit is the uplink not the downlink. Every tp has its own uplink frequency.The onboard electronics on the craft do some amplification and frequency shifting for the re-radiated downlink. Soooo if a nefarious state decides to get rid of some undesirable channels all they have to do is point a suitably sized uplink dish at the craft carrying the undesirable channel and fire a signal at it on the tp uplink frequency for that particular frequency.
