There are many cases where self-installation of a satellite dish or satellite system is better, easier and cheaper than calling a professional installer.You could be doing a self-installation of a satellite dish for FTA satellites or pay-tv subscription TV satellites from scratch, or you may need to re-align your dish because heavy winds on a stormy day blew off your dish causing a misalignment.
You should also do the LOS for each satellite you want to receive bearing in mind that the signal comes from a different direction than the one where the dish points to.
You can use the obstacle marker (the little green balloon) to check for line of sight (LOS) to the satellite.
There are even features for doing a self-installation of a multi-lnb dish (such as the 5LNB Direct TV, Dish Network 1000 dishes or Wavefrontier Toroidal T90 dishes), or a motorized system (with or without USALS).
An obstacle calculator also indicates whether there may be any Line of Sight issues (LOS, and yes, it’s Line of Sight and not Line of Site) due to adjacent trees or buildings.
Now move the obstacle marker directly over the trees and you’ll see d=50m (the distance from the dish to the trees) and h=26m (maximum height of tree above dish for clear LOS).
Your dish is on the roof of your house, at 4m above ground.Once you’ve obtained all these values from this site, preset the elevation and dish skew and point the dish at a landmark indicated by the alignment line on the map. On the receiver, check the satellite signal strength and the network ID of the transponder; it should match the satellite you intend to receive.Move the dish slightly to the left/right and up/down in very small steps and very slowly and watch the signal strength bar on the receiver to do the fine-tuning.Additional features are the charts of available satellites and TV channels, a dish size calculator and footprint maps.When aligning a dish, you need to know the look angles such as the azimuth, elevation and LNB skew.The footprint charts provided by the satellite operators are just a rough guide.
