Many TVs and TV viewers will experience poor reception (pixilation) throughout the year regardless of what the weather is doing outside, but the long sunny, warm days are sometimes uniquely responsible for producing poor picture quality.

For a couple of reasons, this summer of 2020 is very unique. Firstly, the UK has just experienced one of its longest, driest warm Springs in living memory which has meant that the usual, early spring foliage growth spurt was largely delayed this year until the rain started falling again from the middle of June onwards. Secondly, and because of the Covid19 pandemic and lockdown many more people than usual have relied on their TV as a source of information and entertainment.

Deciduous trees coming back into leaf and putting on a spurt in growth can often be the cause for a relatively rapid deterioration in signal quality if the line of sight from the TV Aerial to the TV transmitter is obscured. Even evergreens such as the fast-growing leylandii conifer can put on a substantial growth spurt, not just upwards but sideways too. The likes of wisteria and other creepers on the same wall as a satellite dish will often smother the face of the dish over a short period of time, given the right conditions.

A TV Aerial that’s had its view towards a TV transmitter impaired by a tree or foliage can often be redirected towards a transmitter that has a better line of sight. Satellite / Sky dishes that suffer the same problem can sometimes be moved higher on a wall or even sideways across a wall, cutting or pruning the offending obstruction is also often an option.

TV coax cable and Satellite coax cables which have been exposed to the sun that run down or across a roof will eventually start to breakdown and the outer waterproof plastic coating will become brittle and crack, in turn allowing rain water to enter. On entering the coax the water will then often take the easiest path downwards. Most of the time the water will drip, slowly and relatively harmlessly into the back of a TV wall plate but occasionally and especially if the coax cable is connected directly to a TV or a Sky / Freesat box etc it will enter into the equipment’s tuner, occasionally creating an expensive repair but more often than not the equipment will need to be replaced.

For obvious reasons, any TV coax cable that is exposed on a South facing roof is much more vulnerable to this problem than one which is run down a North facing roof. Coax cable which is in full sunlight on a south facing roof will sometimes start to breakdown in as little as 10 years but cable on a North facing roof can last well in excess of 25 years.
