电视天线放大器是将电视接收天线的输出信号在馈入电视机之前就加以放大的一种装置。为适应普及电视与教学,我们在郊区农村对电视天线放大器作了一些试检。本文介绍的是一个晶体管电视天线放大器。这个天线放大器具有如下优点,适合于农村使用。一、与同类型的电视天线放大器相比,它的结构简单,用的元件少,制作容易,二、可以在设备简陋的条件下装制而无须作特殊的调整,特别是方便于在农村中使用与雄修。三、放大器所耗功率甚少,它可以用普通的干电池作为电源,供电问题简单。
TV Antenna Amplifier is a device that amplifies the output signal of a television receiving antenna before it is fed into a television. In order to adapt to popularization of TV and teaching, we made some tests on TV aerial amplifiers in rural areas in the suburbs. This article describes a transistor TV antenna amplifier. This antenna amplifier has the following advantages, suitable for rural use. First, compared with the same type of TV antenna amplifier, its structure is simple, with fewer components, easy to make, two, can be installed under the device in primitive conditions without special adjustments, especially in the rural areas Use and masculine. Third, the amplifier consumes little power, it can be used as a normal dry battery power supply, the problem is simple.
