Food for thought...
I was trying to get an idea how Solly and Satesco managed to get the spotbeam so far east, so I wrote a program to draw footprint maps. The maps are for a conventional parabola aerial, circular not shaped beam, but are still interesting. Just enter a location for beam centre and the orbital slot and the program draws a map, based solely on maths, not art.
Three lines, blue = 0.5º off axis, green = 1.0º off axis, and red = 1.5º off axis.
Three maps.
1) slotted at 28.2E and pointing at central UK (Birmingham);

2) slotted at 43.5E and pointing at central UK;

3) slotted at 43.5E and pointing 15º east of the central UK.

Just a bit of fun while waiting for 2F to arrive at 28E, so please don't take this too seriously.
BTW, if anyone wants any other scenario mapped just post the orbital slot and the location of the beam centre (as long as it is Europe).
