馈线

kulX一on该线(f eeder)连接天线与发射机或接收机,用以恢送射颇能t的传愉线.发射机的射颇能量通过恢线输送至天线的过程称为馈电,所以馈线通常也称镇电线。 对馈线的主要技术要求有:①馈线与两端连接物之间要匹配,损耗要小,传翰效率要高,②馈线应具备相应的绷带宽度,能承受相应的发射功率能谱;③馈线不应有天线效应,即不辐射或接收电磁波,④施工时,馈线接头安装完后要达到规定的电压驻波系数要求,与两端连接物接触要良好;⑤需要充干澡空气的该线还要注意保持规定的气压,要定期检查是否向外翻气和向内漏水;⑥馈线上下两端的外导体要良好接地(通常接于铁塔架上)。 随所用射频颇段不同,馈线形式也各异,如平衡传箱线,同轴电缆,同轴形、矩形、回形、椭四形波导管等。另外,馈线内外导体之间还有实芯(全介质坟充绝缘)和空芯(介质和空气混合绝缘)之分,实芯比空芯损耗大,但无需充干操空气,多用于无线电中继区间较短、空气中腐蚀性成分严重以及馈线损失要求不商的场合。
