These satellites are in geostationary orbit which means that they are 22,200 miles up-- always directly above the earth's equator.  Two of the DirecTV satellites used in North America are at 103W, and another is a 99W.

Now consider houses at 30N latitude.  If the house is located at 103W, the dish needs to point south (with some elevation).  That's an azimuth of 180 degrees if the azimuth were measured with respect to true north, and closer to 168 or so if measured wrt magnetic north.  If the house is located further west, the azimuth needs to be less. For my area of California, the dish needs to point more in an eastern direction, and the required azimuth is 146 or more like 131 wrt magnetic north.

Cordova is shown as needing an azimuth of 103.8 (magnetic), or about 130 wrt true north. In other words, it needs to point within 5 degrees of south east.
