Previously I had a 120cm. I'd like to know if it possible to buy this unit from Italy. You should switch to horizontal polarization, adjust the Skew-function to a readout between the highest and lowest readout and then turn the whole feed for some degrees to the right or left until you get a good signal. Check the opposite polarization. If you have here a weaker signal, just try again in turning the feed until both polarization are at a maximum and equal.
