“中新一号”C波段信号,目前是亚太地区上空最强劲的卫星电视信号,因此可一改过去的收视C波段信号一定要使用大口径天线的观念,加上数字节目的开播,使得天线的口径更可大大缩小,很多人也都在尝试使用小口径天线收视C波段数字节目。有人用0.75米的偏馈Ku天线或用0.6米正馈C波段天线收下了该星上的C波段的数字节目,而我地处于东经117.5度、北纬24.8度的有利位置上,经过多次用0.6米Ku偏馈天线收视该星上的C波段数字节目,均未能如愿,但用0.9米的Ku偏馈天线很容易地收下了C波段的数字节目。
The “CINC-I” C-band signal is currently the most powerful satellite TV signal in the Asia-Pacific region. Therefore, the idea of using a large-caliber antenna must be changed in the past when viewing C-band signals. With the launch of digital programs, the antenna Caliber can be greatly reduced, many people are also trying to use small-caliber antenna ratings C-band digital programs. Someone took the C-band digital program on the satellite with a 0.75 meter biased Ku antenna or a 0.6 meter positive C-band antenna while I was at a position 117.5 degrees east longitude and 24.8 degrees north latitude, With the 0.6-meter Ku-biased antenna viewing C-band digital programs on the satellite, none of them was able to do so, but the C-band digital program was easily accommodated with a 0.9-meter Ku-biased antenna.
