Ground plane 1/4 lambda antenna
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).
GP antenna is composed of two main emitter parts (vertical part), radial (horizontal part) and coaxial connector (mainly creating mechanical support).
Antenna socket connector is panel mount UHF connector and antenna plug is UHF coaxial connector.
