160m天线！哪位老大再给点建议！ [复制链接]

按ba7io老师的方法用鱼竿弄了一个！效果不理想！

还有别的天线么？

看到了个这个不错！价格高，架设条件更为艰巨！

550刀！忒贵了！ :d

上面的无非还是gp天线的形式，有电容顶，地网不太好，有匹配网络免调谐。既然要玩160m，不如就搞单波段的，振子越长越好，地网可以用软线拉，比商品天线那一丁点地网效果要好。难度在于机械部分。

谢谢哥哥！

来个10米加强鱼竿再想想招数！

继续努力！谢谢哥哥支持！

用多波段方式加感来缩短主长度试下。如20,30,40,75,80,160,在同一主杆上,这样可能短些,但调试会麻烦,但你只要160米波别的波段不调也可

40/75/80/160米四段，总净高度12米应该可接受了。

黎老师好！只要160m要能坚固80m最好！好搞么？ :o

等待使用报告

可找一下广电的朋友，中波广播正在推广小型化发射天线，弄点资料来参考参考。
