Oh yes, I am pleased with the result ! Noise level is now down to the S2..S3 level (from S7 before). I am hearing many more stations, which were covered by noise up to until I installed these common-mode chokes. In the evening times I now hear many more U.S. stations, which were frequently buried by noise before. So as this is my only wire in the air, I use this same antenna for receiving DRM radio stations. Reception always suffered from the noise level around. Improvement here is fun now again. Overall DRM quality has become much better. I found the most improved band however is the 30m band. Even though not designed for 10 MHz, I frequently listen there. Noise level has been around the S9 level, but now it seems completely gone. Matching of the antenna has not changed by the chokes, so I can transmit as before. The price for this improvement has been around 16 Euros for all.
So installing common-mode chokes is not only helpful with keeping RF away from the cable and of course from the shack. It can - like in my case - improve reception dramatically.
哦，是的，我很高兴的结果！噪音水平降到现在的S2..S3级别（从S7之前）。我听到更多的电台，而被蒙上噪声高达直到我安装了这些共模扼流圈。到了晚上的时候，我听到现在有更多的美国站，经常被埋葬的噪音了。所以，因为这是我在空中只能线，我用同样的天线，用于接收DRM广播电台。接待处始终受到来自周围的噪声水平。这里的改进很有趣现在又。总体DRM质量有了很大的改善。我发现不过最完善乐队是30米的乐队。即使未设计用于10MHz，我经常听那里。噪音水平已遍布S9的水平，但现在看来完全消失了。天线的匹配也没有被电抗器变了，所以我像以前那样可以传输。这个价格对于这种改进已经有16欧元的全部。
所以在安装共模扼流圈不仅与RF保持距离，当然从电缆，并从窝棚帮助。它可以 - 就像我的情况 - 改善接收效果显着。
