Without your usual nonsense. The red one: http://en.wikipedia.org/wiki/File:Dipolefeedrad.png I know I'm asking the impossible here, but maybe just this once you could answer a question clearly and directly. I assume that Joel dipole is feed with a coax. Because: "Many people have had success in feeding a dipole directly with a coaxial cable feed rather than a ladder-line. " What is a "Joel dipole"? Is it the Joel case? Do you agree that such "dipole" is the monopole? S* No, you are an idiot. The antenna type is NOT determined by the feedline. |

There must be a balun between the coax and the dipole. The balun only improve the monopole . The only one leg is red (radiate): http://en.wikipedia.org/wiki/File:Di...ebandbalun.png The color someone used in an illustrative diagram has no significance in the operation of the antenna. Both the halves of the dipole are involved in the radiation. If it is feed by the two wires transmission line: http://www.deltadx.net/ABCDx/Sections/Antennas.htm http://www.deltadx.net/ABCDx/Section...le-Ladder2.gif S* |

READ your own link. If a dipole is fed with coax AND if there is NO balun device, then common mode current flows on the outside of the coax and the coax ALSO radiates. If a dipole is fed with coax AND if there IS a balun device, then there is no feedline radiation. In either case, the dipole radiates from both halves. That is what your link says happens but you are too stupid to read it and can only look at the pictures and misinterpret what they mean. |

That may be true, however you appear to be too stupid to understand any of them and just misinterpret the pictures. Your latest babbling nonsense about the page at: http://www.deltadx.net/ABCDx/Sections/Antennas.htm proves you just look at the pictures and either don't read or don't understand the text. Are you one of them? S* Am I one of what? If you mean what are MY qualifications to call you a babbling idiot, I have been building and using antennas for about 50 years and have a degree in Electrical and Electronic Engineering. How long have you been building and using antennas and what degrees do you have? |
