The coordinates are slightly different for every location. That doesn't matter as the installation procedure walks you through it pretty easily.
Take a compass and a protractor (if you can find one in your desk drawer) and determine if you can get a signal BEFORE you commit to service. Hold the protractor as level as you can and try to determine 32 degrees of elevation in the SW sky. You MUST have a clear line of sight to the satellite! No trees or other obstructions. DirecTV has 3 satellites. Depending upon whether you want all kinds of PPV stuff you may need a multi-satellite dish. I have DirecTV. I bought it at home in Mass and installed it myself at my Island location. I got the Boston local channels with the package. They are on the same satellite as the regular programming. As previously stated, the NH and ME local channels are on a different satellite lower on the horizon and more difficult to get. You can put DirecTV on seasonal suspend over the winter or you can take the box home, buy another dish on EBay (15-30 bucks) and use it at home. The only tough part is the aiming of the dish to get it right on the satellite. You have to be VERY patient when first setting it up. It took me some time, but I finally got it.
