打算试一试A证仅有的DX手段，本来打算手搓一个机器和天线，没想到赶上box6开车，就先上车机器，手搓天线进度提前

[upl-image-preview url=https://storage.hamcq.cn/2024-08-26/1724637386-912617-image-1724637352647.jpg] [upl-image-preview url=https://storage.hamcq.cn/2024-08-26/1724637400-941562-image-1724637346020.jpg] [upl-image-preview url=https://storage.hamcq.cn/2024-08-26/1724637414-131-image-1724637341397.jpg] [upl-image-preview url=https://storage.hamcq.cn/2024-08-26/1724637423-473848-image-1724637349683.jpg] [upl-image-preview url=https://storage.hamcq.cn/2024-08-26/1724637386-912617-image-1724637352647.jpg] 材料非常简单，四根1.4m的拉杆天线，4组m4螺丝，塑料板切成条（要硬一些的），4个m4吊耳螺丝，还有4mm内径压接线环，一截带接口的馈线。通过调整拉杆天线的长度以及两组天线之间的夹角（30°-40°）可以调整天线性能，6m波段中心频率驻波比应该可以控制在1.3以内。目前还在改进中，搞个防水盒子什么的。

感谢分享，很少见6m波段的天线。

对了，还有一点……开窗作业一定要把家里的猫关别的屋里，很碍事还不安全[upl-image-preview url=https://storage.hamcq.cn/2024-08-30/1725036295-545993-img-20240830-205807.jpg]

Copying homework: 6m band X-shaped antenna

BI1UDG-711 Could you please tell me what those black, fixed pieces are that sit between the aluminum alloy windows? Would it be possible to provide a link?

What a mess! And to top it off, this antenna is starting to glow.😂
