[QUOTE="DishDick, post: 695263, member: 216974"] Huevos, that is strange so you have to turn dish further away? Strange as obviously it is ok in the UK, but they mostly use the Sky mini dish which does receive a wide beam. Not good that, I cannot jepodise my main channels for this station. Trying to find how to calculate the area of the top of a circle to see how much difference a too large 23mm to 40mm packer on my feedhorn will make to my potential performance. At the moment my dish has a potential reception area of 5,7255526958 meters square and this is being focused on to a feedhorn with a receiving area of 0,004417865 meters square, so if I can work out the effect of the feedhorn being 2 or 3mm too high in the LNB holder, ie the loss of reception area, I can see the theoretical lost reception area, I can then calculate the theoretical % inprovement I could make, to see if it is worth machining the packer. Gee I really must get out more! [/QUOTE]
