Ernie,
The 146 degrees I mentioned is for my house.  I described Cordova as 103.8 magnetic-- as obtained from the DirecTV app-- or about 130 wrt to true north.

I guess I need to be more blunt.  You have a basic misunderstanding.  South is 180 degrees of azimuth, not 90.   So SE is 135, but it is measured as 90 from north to east, and then an additional 45 to get to from east to southeast.  That's why I gave the example of the azimuth required for a dish at 103W.  You can use the DirecTV app with Lamar, CO, which is close to 103W.  The required azimuth is shown as about 167, which is close to 180 wrt true north.
