Sky dishes are incredibly precise instruments. Because the satellites they communicate with are about 22,000 miles away in space, even a shift of just 1 or 2 millimeters at your wall can result in a total loss of signal.
Here is a breakdown of common alignment problems, how to spot them, and what usually causes them.
Unlike old analog TVs that would get "snowy," digital Sky signals either work perfectly or fail noticeably:
You don't always need to go up a ladder to check if the dish is the problem.
Inside the plastic cap at the end of the dish arm (the LNB) is the actual receiver. It doesn't just need to point at the satellite; it also needs to be rotated (skewed) to a specific angle (e.g., -15 degrees). If the dish is straight but the LNB has twisted in its holder, you will get intermittent signal drops, especially in rain.
The most notable reason for poor picture quality is that your actual Sky Dish has been knocked or blown out of alignment.
Your Sky dish needs to point in a specific direction to align with the Satellite. In fact, if you take a look up and down your street you will see all the dishes are pointing in the same direction. This is because Sky/Freesat dishes are aligned with at a specific satellite called Astra 2D at 28.2 degrees East of South.
Finally, the dish needs to be aligned vertically at an elevation between 21 to 27 degrees. There are some products on the market that will help you find the Astra 2D satellite, but due to the complexity of the task we strongly advise calling an engineer to realign it for you.
