This magnetic mount Anglemeter has 0.1 degree accuracy and a large dial face, allowing dish elevation to be read directly.
The most important aspect of installation is dish placement. Obviously the dish must be able to point in the right direction to receive a satellite signal. With satellite dishes, "near enough" is most definitely not "good enough." An error or 1° - or even less - can make all the difference on Earth (or off it!).
The "view" to the satellite must be clear of all obstructions. Generally this means locating the dish away from trees, fences and buildings that might obstruct the line of sight to the satellite. As we mentioned last month, a dry tree usually makes only a marginal difference to satellite reception. The smallest rain shower, though . . .
In order to find the best location, a decision has to be made as to which satellite(s) are to be received. The pointing co-ordinates for the desired satellite can be determined mathematically. These days, computer software makes this task relatively simple. We'll look at software shortly.
