Well the issue was still persisting today and optimal skew did not solve it. Coincidently it all started to happen when the temp started to go above 30 degrees celsius here , for the last week only, and the bottom of the Dish is located only a few inches away from the ground. Non of the other Hispasat installs I have done for friends are having any problem at all. So I decided to try another Dish but this time on the south facing wall as normally they are installed and it works perfectly after that I even rotated the affected Dish w/ LNB 180 degrees and it started to work also but then rain and snow is going to accumulate later creating another problem. So in other words this summer have been "different" for this particular dish due to the extreme persisting heat this year because last year it worked ok all summer long. Funny thing though , the infamous CW-600 premium , was the only receiver throught the house that was able to work ok , the rest of the other 2 coolsats and 1 viewsat showed No signal for the past week. And the CW-800 even has a diplexer on it sharing an OTA antenna.!!!!
Well now I know better no more dishes so close to the ground then!!!!. You could hardly notice that 80 cm Dish in the patio!!! and that is why it was installed there. It looks so ugly on the wall now!!!!, lol, but what to do.
