先の21号の時に4エレ5バンドクワッドアンテナの，18MHzのリフレクターが切れた<\/a>ものの，<\/wbr>修理の足場になるところにアシナガバチの巣があって，近寄ると警告してくるので，修理しないで使って<\/wbr>いました．若干18MHzでF\/B比が落ちましたが，<\/wbr>飛びに大きな影響はありませんでした．<\/p>\n

今回の台風24号では，目視点検したところ，18MHzのエレメントの外側にある14MHzのリフレクターが断線してしまいました．<\/p>\n

\"\"<\/p>\n

もちろん今回の台風の影響だけで切れたわけではなく，長年の疲労がたまっていたところ，今回の強風がきっかけで切れたということで，ある意味寿命ではあります．<\/p>\n

今回もリフレクターが切れただけでは大きく性能が低下することはないと思いますが，<\/wbr>ぶらぶら切れたエレメントを垂らしたまま使用して，<\/wbr>どこかに絡まったりするとめんどうなので，<\/wbr>ハチが死滅して修理ができるまでアンテナを上げないことにしまし<\/wbr>た．ちなみに，<\/wbr>18MHzだけが切れた状態ではうまい具合に14MHzのエレメ<\/wbr>ントに軽くからんだりしてそんなに危うい状態ではありませんでし<\/wbr>た．<\/p>\n","protected":false},"excerpt":{"rendered":"
