德國Schwarzbeck BBHA 9120 寬頻喇叭天線(Broadband Horn Antenna)在其正常工作頻率範圍內擁有非常低的駐波比(SWR)和寬廣的頻寬(broad bandwidth),展現出優良的規格特性。不僅如此,該天線的增益(Antenna Gain)高達18 dBi,這主要取決於喇叭天線的大小與外型。增加天線增益有助於補償連接線的線損。BBHA 9120 系列喇叭天線適用於發射和接收,其發射功率由天線的N型接頭(N type Connector)決定。操作手冊(Operation Manual)詳細介紹了該天線的增益(Antenna Gain)、天線因子(Antenna Factor)、天線駐波比(SWR)及場型指向性(Direction Pattern)。
The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
