[QUOTE="Pietclock, post: 788826, member: 376200"] This was pure coincidence ! Astra 2D's beam was never intended to be a spot beam to exclude certain areas, it's antenna is a simple unshaped reflector. Astra 2D's beam was so tight to focus the low TWTA power to the UK. Same was done with the same satellite type for Germany - Astra 3A. Both are the same type of satellite. The simple design of those satellites produces sidelobes... they are not intended or planned. The new satellites like 1N or 2F will use shaped reflectors... [/QUOTE]
