[QUOTE="gambit, post: 859319, member: 304438"] [FONT=Arial][B]Predicted 2E "UK Spot" Shifted 15 degrees East[/B][/FONT] Following my previous post, I include an attempt at a prediction of the UK spot footprint given the current 43.5 east position. Again, the prediction is based on a 2.6m diameter antenna. The red lines show the 1st, 2nd and 3rd predicted nulls. [CENTER][ATTACH=full]59016[/ATTACH][/CENTER] The map is for a satellite positioned at 43.5 east and assumes that its orientation is the same as for a sat at 28.2 east. Therefore, I have assumed that the longitude of the central spot is shifted 15 degrees east from the UK to about 13.5 east (NE Germany). The specialists on this forum may be able to collate their measurements of the current 2E transmissions with this map. The 1st null runs down the SW corner of the UK, through France, then follows the west coast of Italy. The 2nd null passes close to Israel. That seems inaccurate given Solly's reception of the UK signal in Tel Aviv (11th Oct). [/QUOTE]
