TV 1000 is on both 11823V and also on 12034 on 5.0 east
they are both on the Kn transponder footprint beam to the generally the baltic and far nothern zone areas of Europe.
Normal reccomended dish size in your area for reception would be 1.8 mtrs with a 0.5/6 db lnb etc- this delivers reliable reception including a small allowence during change in local weather conditions.
However there are many reports from invididuals close to your area that utilise a 1.2 mtr are happy to accept that when it rains or at certian periods of the day that it will not be availiable.
What equipment do you have currnetly?
