Number one tip:- at the very least change the LNB, the old one will be well past its sell by date! The old LNB will have a signal to noise ratio well in excess of any new LNB, even the cheapest available now are just a fraction of the noise figure of the ones from a few years ago. Trying to use an old type, can cause problems when you install your new receiver, with high or low frequencies, drifting or even no channels at all. Ideally change the dish too, modern high accuracy dishes need not be as big as the old analogue dishes. This is true of TNT, FranSat and free channels from France, all over the Uk.
