Who ever said a balanced transmission line does not create an EM field? Here is an illustration of the EM field of a transmission line... https://rdl.train.army.mil/catalog-w...p3.htm#fig3-14 -- Rick |

What is depicted is NOT an electromagnetic field, i.e radio waves. It is an illustration of an electric field and a magnetic field and is correct in that aspect. It is also from a dumbed down US Army training publication and I can show you lots of Army manuals that do not conform to accepted principals and language usage left over from my days as an Army instructor. -- Jim Pennino |

Now I begin to understand where the boundaries of your knowledge lie, and why you present yourself as a redneck when you hit those boundaries. You are another to whom I exhort a study period leading to an understanding of Maxwell's Equations because ... 1. Whenever there is a changing electric field, there is also a changing magnetic field and hence an electromagnetic field. 2. Whenever there is a changing magnetic field, there is also a changing electric field and hence an electromagnetic field. That will suffice for the moment. Meanwhile, write out longhand 1000 times, "Jimp must not be cheeky to his teacher". Please be aware that there are two versions of Maxwell's Equations, one for in vacuo, and the other in a media, because a notorious Brit redneck has recently made a fool of himself in that respect. In conclusion, Old Chap, it is far better for the health of amateur radio in general, and this NG in particular for you to engage in gentlemanly discussion than it is to present yourself as a disruptive redneck. |
