Had the same trouble to start then found out dish angle not correct, lean the dish back from vertical 2-3 degrees makes a lot of difference. can also by a sat signal strength meter for about £10-£15. signal direction can be found on dishpointer.com - google map pinponts your house and which direction satellites are in relation to you. I'm 65 if I can do it anybody can.
