A bracket assembly is provided for attaching to a mobile computing device. The mobile computing device has a use range at which the mobile device is typically positioned when in use. The use range varies between a low end angle and a high end angle. The mobile computing device also has a housing having a reference plane. The bracket assembly is configured to support a first antenna at a first angle and a second antenna at a second angle, each of the first angle and the second angle being measured with respect to the reference surface when the bracket assembly is attached to the mobile computing device. The first angle is selected so that the first antenna is in a vertical plane when the mobile computing device is positioned at the low end angle. The second angle is selected so that the second antenna is in a vertical plane when the mobile computing device is positioned at the high end angle.
