I am in the process of fitting a new TV aerial up in the loft.
Need to point it at the local mast, fortunately in line of sight where we live.
Unable to see the true direction once in the loft, I asked my 27 year old lad " Have you a compass app on your phone "
Back come the reply " No but I have a spirit level app, will that do "
Dohh
I'd expect a 27 year old to climb up into the loft and do it for me.
