From various feedbacks I gathered that is not only used to find the alignment of a satellite dish but also to check the line of sight, i.e. if there are any obstacles in the way between the dish and the satellite. As you may all know, with satellite reception there must be clear line of sight. Obstacles such as trees or nearby buildings can severly reduce or even block the signal. The maximum height an obstacle can have depends on the the distance from the dish to the obstacle and the dish elevation at your specific location (the further away the satellite is from you the shallower the dish elevation becomes). So, in order to know how high an obstacle can be, I added a few days ago another little marker to the map. The green marker is supposed to resemble a tree. If you move that one the distance between the dish and the obstacle is given together with the maximum height the obstacle can have. This height is measured from the lowest point of the dish. For example, if your dish is attached to your roof at about 4.00m, you’ll need to add this to the given obtacle height to get the total height from the ground. I think it’s pretty clear. Hopefully, this way you can judge whether the tree opposite will really affect the reception and you’ll get some clues where to best place the dish.

    Hi! Wow it’s a amazing tool! it is possible to add toroidal dish support?

    Possibly, yes. I’ll add it to my to-do list.

    This is a fantastic tool. I am about to install motorized dish and wondered how the house to the south of me can block my view. Placing the “tree” where the house is and trying a bunch of birds, I am now certain that my view is ok. Thanks to you.

    Pretty nice, would also be nice if it calculate the altitude of the terrain to compare to max object hight, I live at 82 meters above sea level with a bunch of south high hills.

    Would be cool to select Metric or English systems, but otherwise very nice indeed. Maps needs some way to 3D angle the view or get closer. I had an install scheduled this morning but they couldn’t find a spot– I’m fenced in by trees. May trim but with this it might be okay on the garage.

    I’m planning to give the distances in feet for all US addresses as per default. Will do that with the next update.
