卫视烧友们曾经采用玻璃钢复制卫星抛物面天线,不过制作的工艺要求较高,有一定难度和危险性,而且所用的化工原料一般也难以购得,这里笔者介绍一种用普通的水泥砂浆制作卫星天线的方法:1、取一面完好的整板正馈天线,将其LNB支架、底座托盘支架拆除,只留下抛物面“锅”面,将“锅”面反扣放在地面上作抛物面模具使用,然后在上面涂刷一层脱模油(废弃机油亦可)。2、取8号铁丝剪下多根,弯成弧 Satellite TV fans have used glass fiber reinforced plastic parabolic satellite dish, but the production process requires a higher degree of certain difficulty and danger, but also the use of chemical raw materials are generally difficult to buy, here I introduced a common use of cement mortar satellite production Antenna method: 1, take a good whole board feed antenna, its LNB bracket, base tray bracket removed, leaving only the parabolic “pot” surface, the “pot” surface anti-buckle on the ground For parabolic mold use, and then brushing a layer of mold release oil (waste oil can be). 2, take the No. 8 wire cut a lot of roots, bent into an arc
