Westpeople

We are in Ariege on the edge of the Pyrenees and have a marginal signal on a standard SKY minidish which degrades on 2D channels in rain. I will be buying a larger dish when I return in March but wondered if there is a means of adjusting the skew ? I have checked a lot of the previous postings but skew is never mentioned in the indstallation details but from UK installation experiences on other satellites I know it can be critical with a low signal.
