I set the elevation as stated for a place near me on the alignment chart and used a compass plus mangetic variation to line up and it lit up straight away! Note though that the dish and LNB arm are metal so you don't want the compass near them. Use a straight piece of wood across the face of the dish and align at 90 degrees from where you are aiming at if you follow me so you can get the compass in free air away from the dish. For the rest I'll leave it to the experts. Don't fancy your deadline for putting it up this week! Hope the weather gives you a break to get it done
