摘要
本文对楼顶电视发射天线的优缺点进行了评述。介绍了带反射板偶极天线阵的辐射近区场的近似计算法的数学模式、计算结果和实测数据。对楼顶电视天线适用于哪些电视台,特别对在发展中的城市架设永久性楼顶电视天线问题提出了一些看法。
The advantages and disadvantages of mounting TV transmittingantennas on tops of tall buildings are discussed.Mathematical model ofapproximate computation of near radiation field of dipole array with reflectingplate,the results of computing and measurd clata are introduced.Commentsare given on which kinds of TV transmitting stations are suitable for usingTV antennas mounted on tops of tall buildings and on the problems ofmounting permanent TV antennas on tops of tall buildings in developingcities.
