One of the main factors affecting indoor reception are the losses produced by building walls, partition, windows, metallic elements, etc. The ability of electromagnetic waves to pass through materials is called pervasiveness, it is related to losses, and it is highly dependent on the kind of material and its thickness. As a rule of thumb, the higher the pervasiveness the better the signal will reach, and from low to high pervasiveness the scale would be metal, concrete, brick, plasterboard, wood and glass. Also, electromagnetic waves suffer from reflections in indoor walls, and these reflections are superimposed on the wanted signal, causing fading and severe impairments. To improve indoor reception, the receiving antenna should be installed as close to a window as possible, avoiding metallic elements and with clear line of site to the TV transmitters.
