61.5 is generally in a southeast direction and 148 is generally in a southwest direction. The angles vary depending on where in the country you are. You can't view both of them with the same dish - they are waaaaaayyyy to far apart.

Yup - the 61.5 bird will have a very low elevation angle in the LA area. You'll probably have a much easier time pointing at 148.
