For any of us visiting RV Parks across the nation, one of the first things we do upon arrival is to set up our satellite systems.
This APP, DishForMyRV helps show us where the satellites are in the southern sky.
Once you open the application on your iPhone, you simply start by pointing towards the southern sky until you spot the three (3) satellites used for tailgater's.
These will be marked 110, 118, and 129. At this point you need to use the cross hairs in the middle of the screen to line up with the image of each of the satellite(s) to ensure that there are no obstructions, like the tree's in this image.
You should be doing this from the spot where you have placed your satellite dish, and from the front of the dish itself.
Its a great app, as it has helped me many times get a better spot for the dish that I would have picked otherwise.
The cost is $9.99 and is available on the Apple App store.
