The carbon fiber fishing rod itself acts as the antenna element. Believe it or not, this is an interesting antenna. TU 73

@ are you sure it’s not only the wire that tuned?

@@forgetyourlife The carbon fiber fishing pole itself acts as the element. The wire that powers the fishing pole from the ATU is about 2 feet long. The fishing pole, about 20 feet long, acts as the antenna. Using this antenna, I have contacted 52 DXCC entities in CW communication. Amazing!
Francois Dupont san Thanks for your comment. This antenna consists of two parts, one is the carbon rod and the other is ATU; Automatic antenna tuner. This carbon rod works as an antenna. No need to use an ordinary wire antenna. In these days, JS1WWR one of the Japanese Amateur radio station had developed this type of antenna. The carbon rod is very light weight and easy to handle. I use 6 to 7 m long carbon rod, it is very light. JS1WWR use 13m and more long carbon antenna on the top of his car. If you use an ordinary glass fiber rod and wire, it is very hard to handle and need to prepare the huge antenna base. In common understandings, the carbon rod is not suitable for antenna itself. But, JS1WWR had discovered the carbon rod is very good characteristics under the specific conditions. I am not a specialist in those areas. I only explain it roughly. This carbon rod antenna is good listening ability. Quite very low noise. It may work as a noise filter. There are so many signal noises In a city or crowded area. JJ1XTG had tested the carbon rod antenna and the other ordinary antenna. He said, very easy to capture DX signal. Easy to listen. He had also tried to participate in ARRL contest and got tremendous results. He use 100W power and his signal have reached to US west and sometimes reached to US east from Japan. Some of the Japanese Amateur radio stations have just started to use this type of antenna recently. I am not sure why this type of antenna well works. But, I think the Amateur like to challenge new era. So, I also have started to try one. Now, I am struggling to adjust my carbon rod antenna. Good tuned one is very well works. JJ1XTG named it "WWR ANTENNA" with admiration to original developed by JS1WWR. I am not a specialist. I am just a follower. If you have any question, please feel free to ask me. De JA1BJT 73 TU
