For little money you can buy here a Octo LNB allows for direct connection of 8 receivers due to the internal switch. I assembled it myself at my bowl, and aligned first time after sight. A little tip for this purpose: [...] Here bears to his address in the form of "city, Street number", selects the satellites (Astra 19.2E) and then get on a Google Earth image, the orientation of the bowl displayed. Having aligned the dish so by sight, I have re-adjusted with a Satfinder and my receiver was full Auschlag with perfect digital reception. Good LNB.
