3. IS THE DISH ASSEMBLY LEVEL? How often is your campsite completely level? Because of the sensitivity of the satellite system, if the dish is set-up on even slightly uneven ground, it can put the dish alignment out by as much as 7 degrees — enough to prevent you locking onto the signal. You must ensure the dish is as level as possible. Using thin wood chocks to raise the stand slightly will allow you to make the fine adjustments necessary. Tripod-style stands may have a small bubble level in the top of the pole to assist. If you have the fixed-frame style of dish, you will need to use a spirit level on the frame to achieve the same result. 4. CLEAR LINE OF SIGHT In most cases when I have struggled to obtain a good signal, I’ve traced the problem to an obstructed line of sight to the satellite. You would be amazed by what can affect the signal quality. Trees are an obvious obstruction but even a tree that is 50m away can significantly reduce the quality of the signal. If you are on the west coast of the country, you will find the shallow angle of the dish will mean other objects closer to the ground will get in the way. 5. MOVE THE COMPASS It’s amazing how many times I see owners standing next to their dish with their compass trying to align it in the direction of the satellite only to find they cannot receive a signal. Most satellite dishes are made of steel, which is magnetic, and it will cause the compass to point away from north. It seems like a simple mistake but it’s one owners frequently make. If the dish is even slightly off-level, the elevation will be out by a few degrees. To overcome this, set your compass to the direction required and stand in front of your dish with the north pointer aligned on the compass dial. Walk away from the dish in the direction required for at least 5m. Turn 180 degrees until the south pointer of the needle is positioned where the north pointer was. This gives you a back bearing and should align directly back to the dish. Mark the spot with a small rock or similar and go back to the dish. Now ensure the arm of the dish is aligned perfectly with the marker. Your dish will now be pointing in the right direction with a high degree of accuracy.
