"NM5K" napisal w wiadomosci ... Fer instance, I'm sitting out in the woods up at my recreational living center.. I have dipoles strung up in the trees which I leave there, and I roll the rg-58 coax up and hang it on a tree branch when I leave. Not a ground wire, or ground connection in sight.. And works perfectly well. Of course, you can't really see the wires here, but "S" can trust me, there is no ground connection. The radio is sitting on that stone bench, and the only connections are 12v to my car battery, Where is the car battery? On the stone bench or in the car? S* |

But to answer your question, I open the hood of the car, and attach the wires to the battery while it's in the car. That way I can start the car to charge the battery every once in a while. But the power source of the radio has nothing whatsoever to do with the antenna. I could place the battery anywhere and the operation would be the same. The car is not part of the antenna. The *complete* antenna is suspended between a couple of oak trees well over my head. The antenna is decoupled from the feed line. And there are no connections to ground. One could consider the negative power lead as connecting to a "chassis", IE: the body of the car, but that is a DC connection, not RF. Moving the battery would make no difference whatsoever in the performance of the antenna. |

Moving the battery would make no difference whatsoever in the performance of the antenna. "Would" means that you are not sure. If you want to be sure you can make the two experimments: 1. Take off the car battery and sit it on the stone bench, and/or 2. Instal the ammeters on the each wires to the battery while it's in the car. Would be nice to know the results. Best Regards, S* |

"Would" means that you are not sure. No, "would" means just that. And I am sure. If you want to be sure you can make the two experimments: I'm already sure. I've run more portable stations over the years than you can imagine. With batteries in and out of the cars, using various types of "complete" antennas, and also using the vertical antennas on the vehicles. Even if I use an antenna on the vehicle, which *would* use the car body as part of the antenna, where I have the battery or radio makes no measurable difference in antenna performance. |

Let's not worry about Szczepan's misunderstanding of the word "would". I like the idea of the ammeters - I think I saw something similar in a textbook I have from the 1920s or 1930s. Best wishes to all, Ian. |

Meaningless babble. Moving the battery would make no difference whatsoever in the performance of the antenna. "Would" means that you are not sure. Nope. He is sure, I am sure, and everyone that knows anything about RF is sure. The only one in the dark is you. If you want to be sure you can make the two experimments: 1. Take off the car battery and sit it on the stone bench, and/or 2. Instal the ammeters on the each wires to the battery while it's in the car. Would be nice to know the results. Been done innumerable times; it makes no difference. You are a babbling idiot. |
