Hopefully understanding of our users for the inconvenience caused. Make sure you set the dish correctly to get the maximum signal strengths. The wanted signal will have ,nb broad ill-defined maximum, the cross pol signal will have a sharp narrow null. I got the pol skew angle from the Service Provider.
To start discussing the satellites polarisation is confusing. I just want to return to this topic for a sec. If you are in the southern hemisphere and facing north east then you need to turn the feed by an amount clockwise, as viewed while standing behind the dish and facing forwards towards the satellite in the sky.
The fat lump needs zkew be always towards the feed support arm. When your dish is pointed almost straight up the elevation angle is nearly 90 degrees. And for me it’s easier to understand skew if I’m behind the dish. Satellite Dish Ln Tools. Zoom in for better accuracy.
