Don't forget that the polarization of the signals is 'skewed', so they
don't arrive exactly horizontal and vertical. The LNB will need to
mounted so that it is also skewed (rotated in its mounting clamp). In
the case of the 28 degree east satellites, the skew angle is around 13
degrees clockwise, looking towards the dish.

Useful info; thanks.
