Again, like the radio, when you really get tuned very precisely onto the frequency, the static goes away and you can hear subtleties in the signal that you couldn't hear before.
再一次，以收音机作比方，当你极其准确地调到那个频率上时，杂音消失了，你就可以听见讯号中过去听不见的微妙之处。
In one exemplary embodiment, the multi-band antenna system 100 is tuned to operate within two general radio frequency ranges which are generally referred to as a low band and a high band.
在一个例示的实施例中，多波段天线系统100被调谐为在两个通常的射频范围内操作，这两个通常的射频范围通常称作低波段及高波段。
