I have a 1.8m dish to receive Sky TV, and subject to weather conditions, we receive a good signal up to about 10.00pm (except for ITV which disappears about 5.00pm).  My problem is that when the electric trips, because you switch the kettle on when the washing machine is on (!), we loose the satellite signal.  It can take up to 24 hours to get the signal back.  Does anyone know what the problem is we have?  We had the LNB and dish professionally aligned.
