Ｋｕ波段是直播卫星频段。它有很多的优点：（１）Ｋｕ波段的频率受国际有关法律保护，并采用多馈源成形波束技术对本国进行有效覆盖；（２）Ｋｕ波段频率高，一般在（１１．７～１２．２）ＧＨｚ之间，不易受微波干扰；（３）接收Ｋｕ波段的天线口径尺寸小，便于安装；（...
Ku band is direct broadcast satellite band. It has many advantages: (1) Ku-band frequency is protected by international relevant laws and the multi-feed forming beam technique is used to effectively cover the country; (2) Ku-band frequency is high, generally in the range of (11.7-12). 2) between the GHz, less susceptible to microwave interference; (3) receive the Ku-band antenna aperture size small, easy to install; (...
