为解决隧道内数字电视信号的覆盖问题，可以采用天线方式和泄漏电缆方式，文中对这两种方式进行了理论分析和实际测试比较，并介绍了两种方式各自的优缺点和适用场合。

Abstract

In order to solve the coverage problem of digital TV in tunnel

we can adopt the antenna or radiating cable. In this paper we made comparison between the two modes according to theoretical and practical test. We also introduced the advantage and disadvantage based on the two modes

and suitable application of each one.
