Understanding Skew
Linearly polarized satellite signals are transmitted in vertical and
horizontal "waves" offset exactly 90° from each other. Since these
signals are oriented in a precise cross pattern, the TracVision antenna's
receiving element, called the LNB, must be oriented in the same way.
This orientation is referred to as the LNB's "skew angle." The more
precise the LNB's skew, the more signal it will collect and the better
the reception.
