Comments Coverage restrictions are detailed in table 1 and the coverage achieved by an antenna matching the template is shown in figure 2. It should be noted that coverage achieved by a real antenna system will probably be lower. Reducing the antenna height reduces the restrictions required figure 3. Templates for the other channels investigated are shown in figure 4
