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? Instead writting the "babbling idiot" write a long article on antennas without ground. Why as there already exists thousands and thousands of such literature references? Howver you are too much of an ignorant, ineducable, babbling idiot to be able to read any of them and understand them. You were totally unable to understand something as simple as: http://en.wikipedia.org/wiki/Dipole_antenna and started babbling about the colors on the graphics showing you haven't a clue what the article was actually saying. You wrote: "Only end fed monopoles need radials". Do you mean that "Only end fed monopoles need ground"? No, I meant what I said. You, however, are too much of an ignorant, ineducable, babbling idiot to be able to understand it. To be precise, only end fed monopoles need a counterpoise. The counterpoise can consist of either radials, a large conductive area fabricated for the purpose, or the Earth itself IF the surface conductivity is high enough. The words "ground", "radial", and "counterpoise" in relation to antennas are three diffent things with three different meanings but you are too much of an ignorant, ineducable, babbling idiot to be to understand that. A quarter wave, end fed vertical monopole with a set of radials does NOT need a connection to ground. The radials serve as the counterpoise. As you are an ignorant, ineducable, babbling idiot you will not understand any of this and will reply with babbling nonsense. |

The Author in Wiki describes the "dipole" used by radio-amateurs. Such dipole is simply "The quarter wavemonopole antenna". S* |

Are you able to understand something as simple as the above? Yes, and obviously you can not. What it means is the total FIELD is the same as if the antenna were a dipole. Nothing more, nothing less. To be precise, only end fed monopoles need a counterpoise. The radials serve as the counterpoise. The Author in Wiki describes the "dipole" used by radio-amateurs. Such dipole is simply "The quarter wavemonopole antenna". A dipole is a dipole is a dipole and it doesn't matter who is using it. A dipole is NOT "The quarter wavemonopole antenna". A dipole is a dipole is a dipole. You STILL can not understand the difference and you never will as you are an ineducable idiot. How many antennas have you built in your lifetime? |

S* No It doesn't, it describes a monopole as as dipole using the image in the ground as the second leg!! But what is does show is a dipole with one arm connected to the braid of a coax!!!! Which of course you ignored!!!!! The braid = the shield. The braid and the arm are together the counterpoise. Have you the same voltages on the braid and on the coax "live" wire? If not, than you heve the monopole. But it is nothing wrong if in your community it is call "dipole". S* |

A length of cable, whatever cable it is, is not a short circuit on HF. |

... If not, than you heve the monopole. But it is nothing wrong if in your community it is call "dipole". S* Hello Szczepan. The monopole and dipole aerials are definitely two different aerials and it would be wrong to call a monopole a dipole. It seems that you need some help to understand aerials. The ARRL (http://www.arrl.org/shop/Antennas/ ) and RSGB (http://www.rsgbshop.org/acatalog/Onl...tennas_37.html) both sell helpful books on aerials. Kindest regards, Ian. |

The monopole and dipole aerials are definitely two different aerials and it would be wrong to call a monopole a dipole. Monopole antenna: "One side of the antenna feedline is attached to the lower end of the monopole, and the other side is attached to the ground plane, which is often the Earth." Dipole antenna: "A dipole antenna is a straight electrical conductor measuring 1/2 wavelength from end to end and connected at the center to a radio-frequency (RF) feed line. This antenna, also called a doublet, is one of the simplest types of antenna, and constitutes the main RF radiating and receiving element in various sophisticated types of antennas. The dipole is inherently a balanced antenna, because it is bilaterally symmetrical. Ideally, a dipole antenna is fed with a balanced, parallel-wire RF transmission line" The Hertz dipole was symmetrical. The radio-amateurs use the name "dipole" for a monopole. It is not wrong because they do not use the name monopole. S* |

Monopole antenna: "One side of the antenna feedline is attached to the lower end of the monopole, and the other side is attached to the ground plane, which is often the Earth." Yes, and there in ONE element.

The radio-amateurs use the name "dipole" for a monopole. No, they do not, you babbling, ineducable idiot. It is not wrong because they do not use the name monopole. It is nonsense because radio amateurs do NOT call a monopole a dipole. You are a babbling, ineducable idiot. How many antennas have you built in your lifetime. |

The "dipole" where one element is connected to "live" wire and the second to a "ground" is the monopole. Yours "dipoles" are not symmetrical (electrically0. They are symmetrical mechanically. S* |
