-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). ​
