5
When selecting antenna of television attention should be paid to the parameters of this device. One of them is the operating frequency range. Besides, important figures – the directivity factor (indicates how many times the signal of this antenna of television more reference), the ratio of the traveling wave (alignment of the antenna with the cable), the coefficient of protective action (determines the noise immunity of the antenna).
6
Another parameter antenna of television – directional diagram. This indicator characterizes the level of the signal issued by the antenna.
Note
In some cases, to improve the quality of the picture will not work. Even after installing a filter, an amplifier or equalizer image quality will not change, so the only way is to use the professional help of a specialist.
