Our TV aerial is in our loft. Ever since it got moved during some building work we've been unable to get the perfect picture we used to have despite trying every angle. Any idea why and is there an easy way of getting our perfect picture back?
Check the cable fior cuts/abrasions: it may have been damaged by the builders. If you have a circuit tester check at the TV end to see that there is no connection or leakage between inner and outer conductors. Also, of course check for good connections at aerial.
