The area surrounding an NDB [non-directional beacon] within which the strength of the vertical field of the ground wave exceeds the minimum value specified for the geographical area in which the radio beacon is situated.

The above definition is intended to establish a method of rating radio beacons on the normal coverage to be expected in the absence of sky wave transmission and/or anomalous propagation from the radio beacon concerned or interference from other LF/MF [low frequency/mandatory frequency] facilities, but taking into account the atmospheric noise in the geographical area concerned. 2, record 1, English, - rated%20coverage

Zone entourant un NDB [radiophare non directionnel] dans laquelle l'intensité du champ vertical du radiophare, due aux ondes directes, est supérieure à la valeur minimale spécifiée pour la région géographique dans laquelle le radiophare est situé.

Le but de cette définition est de fournir une méthode de classification des radiophares d'après la couverture qu'on peut normalement en espérer, en l'absence d'ondes directes, d'anomalies de propagation ou de brouillage provoqué par d'autres installations radioélectriques LF/MF [basse fréquence/fréquence obligatoire], compte tenu cependant des parasites atmosphériques dans la région géographique considérée. 2, record 1, French, - couverture%20nominale

Esta definición tiene por objeto establecer un método para clasificar los radiofaros a base de la cobertura normal prevista cuando no haya transmisión ionosférica, o propagación anómala desde el radiofaro en cuestión, ni interferencia ocasionada por otras instalaciones LF/MF, teniendo en cuenta, sin embargo, el ruido atmosférico existente en la zona geográfica en cuestión. 1, record 1, Spanish, - cobertura%20nominal
