-Disadvantage, on the other hand, is that the radiation pattern drops sharply to zero at zenith, making it very difficult to detect meteors flying directly over the head (compared to visual observation). +Its disadvantage i that the radiation pattern drops sharply to zero at zenith, making it very difficult to detect meteors flying directly over the head (compared to visual observation).

-The most suitable direction of antenna radial is to the west towards the GRAVES radar where we expect the best reflections from meteor trails.+The most suitable direction of antenna radial is to the westtowards the GRAVES radar where we expect the best reflections from meteor trails.
