Height and dimension of antenna is configurable 天线高度尺寸可调
Altitude of antenna above mean sea level 天线高度距平均海平面
New - designed antenna system uses a retarded wave principle that cuts antenna height 60 % 新设计的天线系统采用了延迟波原理,使天线高度降低了60 %
In this kind of mobile communication systems , the height of transmitter and receiver are always lower than the surrounding buildings . and it makes the traditional propagation prediction models for macrocells can not be used any more 在这些微蜂窝移动通信系统中,基站天线和接收天线高度一般低于周围建筑物高度,典型的电波传播环境是在城市建筑物的“峡谷”中,统计模型的应用从根本上失去了应用的前提。
The company says the burj will fulfill the chicago - based council on tall buildings and urban habitat ' s four criteria for the tallest building : the height of the structural top , the highest occupied floor , the roof ' s top , and the spire ' s tip , pinnacle , antenna , mast or flag pole 公司宣称,迪拜高塔将奉行芝加哥理事会制定的高层建筑和城市人居的四重标准:结构性定点的高度、最高层数、屋顶高度、尖端高度、天线高度和旗杆高度。
