本文通过对采用不同下行频率(如714兆赫UHF频段及12千兆赫频段)的卫星广播电视系统有关情况的分析比较后提出,根据我国现有的具体情况,选用较低的下行频率(如620～790兆赫UHF频段),乃是发展我国卫星广播电视切实有效的措施。
Based on the analysis and comparison of satellite radio and television systems with different downlink frequencies (eg 714 MHz UHF band and 12 GHz band), this paper selects lower downlink frequencies (eg 620 ~ 790 MHz UHF band) is an effective measure for the development of China’s satellite radio and television.
