[QUOTE="MartinP, post: 17139, member: 175361"] Regarding VERY big dishes: It's important to realise that a BIG dish will swamp the LNB with a STRONG signal from the south beam. When this occurs, the signal from 2D will effectively disappear. What you should try to do is to align the dish for the best signal quality from 2D at around 7pm (or when it is weakest). You can use the "Manual Tuning" facility in the secret Installer Menu to set the parameters for, say, ITV. This will allow you to monitor the signal quality on the TV screen while you align the dish and optimise the LNB focal position and "skew" position. Obviously, you'll need the TV screen near to the dish for this method! You can also set up the dish and LNB with a spectrum analyser, provided that you set it for Astra 2D. Someone requested the "What Satellite TV" report on Invacom LNBs? As soon as I get a moment, I will scan it and put it here: Martin [/QUOTE]
