How do you Line up Satellite aerials?

Answer 1

Personally, I have a motorized horizon to horizon mount that tracks the entire visable Clarke Belt. Other than that, you can certainly do it manually. You use your latitude and longitude and the orbital location of the satellite to calculate your satellite dish's look angle in azimuth and elevation. Making sure the dish mount is completely plumb, you set the elevation using the notches in the side and you use a compass (correcting for magnetic declination for magnetic north versus true north) for the correct azimuth position. Also, on linear polarisation satellites, you must also set the skew by twisting the LNB. The more east or west the satellite is from your location, the more skew there will be. Fine tuning with your box's on screen signal display is usually required unless you have an inline signal meter you can use to help you point. I use this web based calculator to find azimuth, elevation and skew:

Pay special attention to what is negative and what is not as some of their numbers they use are the opposite of what's generally accepted to be negative and positive when it comes to latitude and longitude. That same page also had instructions on setting up a motorized dish as well at:

Answer 2

your best option is to buy a "satelite finder meter" approx £18-£20 (try :::www.screwfix.com)
