-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).

 Active element should be placed far enough (at least 2 lambda) from any large or conductive objects such as walls of buildings, wires, railing etc.
-The most suitable direction of antenna radial is to the west towards the GRAVES radar where we expect the best reflections from meteor trails.
