I will get this working. I am determined. I have spoken.
'It' is the digital TV set I bought for the caravan, and which I intend to use in Cornwall if there is no wassailing or pagan rituals to be attended to on any of the evenings while down there.
Today I fitted all the bits together: the dish onto the tripod, which I securely pegged down onto my front lawn, near the caravan; the cable from the LNB to the signal meter; the cable from the meter to the receiver in the caravan; the SCART cable from the receiver to the TV. Then I switched it all on, and trained the dish slowly this way and that, seeking satellites. I found one, and began finer tuning, because you have to get it pretty well exact.
And then the rain came down. Oh, fiddlesticks! Foiled by a downpour! Not only did I personally get a bit wet, reception suffers in the rain so it was no good trying to do much more. In the end it got too dark to continue, and I packed the dish away in my garage and will try again either tomorrow morning or Friday. But time is running out. If I can't get this to work before I go, then I'll have to find other amusements while down in Cornwall!
My next door neighbour K--- came home as the rain and the dark was intensifying, and offered to show me what to do on Sunday. I'm not proud. I will eagerly let him do it and watch closely. I suspect there's a knack to this, and once I know what it is, it'll all be easy-peasy. (You could say the same thing about life in general, now couldn't you?)
