射频信号就是经过调制的，拥有一定发射频率的电波。为了能够在空中传播电视信号，必须把视频全电视信号调制成高频或射频（RF-Radio Frequency）信号，每个信号占用一个频道，这样才能在空中同时传播多路电视节目而不会导致混乱。 射频信号有自己的特点，所以传输信号需要特别的媒介，而相应连接器也很特殊。

迄今积累的所有证据都不能说明基台产生的射频信号会造成任何短期或长期的不良健康影响。
From all evidence accumulated so far, no adverse short - or long-term health effects have been shown to occur from the RF signals produced by base stations.
由于射频信号可能会干扰某些电子医疗装置和导航系统，在医院里和飞机上通常禁止使用移动电话。
Mobile phones are often prohibited in hospitals and on airplanes, as the radiofrequency signals may interfere with certain electro-medical devices and navigation systems.
由于无线网络与基台相比产生的射频信号一般较低，接触这些信号预计不会产生不良健康影响。
Since wireless networks produce generally lower RF signals than base stations, no adverse health effects are expected from exposure to them.
