摘　　要：我院共用天线电视系统属远距离传输,由于地下传输电缆截止频率低而无法使用。我们采用在一个系统中设置三个前端的方法解决了这个问题,并采用多波段放大器的方法调整了大传输斜率、消除了在V频段高端和低端的重影。The common television antenna in our college belongs in the distant transmission. The underground cable couldn't be used because it has a low cut-off friequency. We solved this problem by setting three forth-ends. The great transmission slope was regulated bJ making use of multichannel amplifier. By means of the above methods the double shado- ws in high and low end of the very high frequency were eliminated.
