You are an idiot. The vertical monopole can have only one radial. More radials is necessary for a strong stations. More radials are necessary for a symetrical pattern, elimated feedline currents, reduce ground losses, and a predictable impedence. Do you understand? You understand nothing. The only difference between your monopole and your vertical antenna is the direction. As far as the pattern over real ground is concerned, they are essentially identical. But the feedpoint impedences and feed method are different. Do you agree? You understand nothing. You are an idiot. -- Jim Pennino |

Beware of any inputs from this bialek guy! He appears to be either a troll
or a blithering idiot. If you let him drag you into a discussion of his point of view he will lead you on endlessly and ignorantly!. Irv VE6BP "Szczepan Bialek" wrote in message ... napisal w wiadomosci ... I'm probably known as the anti-ground.. lol.. IE: I don't believe in RF grounds in the shack unless the antenna is fed directly from the shack. Which is fairly rare for me, but I have done it on 160m a few times.. My way of thinking is that an RF ground should always be a part of the antenna itself, preferably away from the shack. IE: a dipole is a complete antenna, and requires no ground for proper operation at the antenna, or at the shack. You don't need an RF ground at all. Your dipole is not the dipole but the monopole with the one radial. In the case of a vertical, the RF ground should be under the antenna if a monopole. IE: ground radials under a ground mount, or elevated radials for a ground plane. Your dipole is a horizontal monopole with the one radial. The vertical monopole can have only one radial. More radials is necessary for a strong stations. Do you understand? The only difference between your monopole and your vertical antenna is the direction. Do you agree? S* With either one of these, no RF ground is required for the shack. Ditto for a half wave vertical, which is a complete antenna. The only worry with it, is feed line radiation, which is a bit different issue. It just needs to be decoupled for the best operation. But that is something to be considered with any antenna, including the dipoles. The only ground I use at the shack is the safety ground for line voltage gear.. All lightning grounding must be at the antenna/mast, and at the entrance to the shack. "ground window". I quit using a shack RF ground in the mid 90's or so.. Ain't missed it all at so far... I actually had more issues when running high power "KW+" with a shack RF ground vs not using one. The use of the ground wire tuning may well help it work better on certain bands to prevent a hot shack. But I consider it a band aid to help hide problems that actually should be addressed at the antenna. Or in a perfect world at least.. BTW, I do not agree with the notion that an antenna needs to be resonant. That is another wives tail, as pointed out by Cecil. Even a dipole that is .05 WL long will radiate nearly all power that is applied to it. And antennas are reciprocal between radiating, and receiving. The trick is getting the power to and from the small antenna without it turning into heat. :/ There can be problems with excess loss, but it's not the element's fault for being non resonant. |

Maybe SB can explain the difference between a monopole with a single ungrounded radial, and a dipole. |

Maybe SB can explain the difference between a monopole with a single ungrounded radial, and a dipole. Each radial, grounded or not (but connected to the shield of the coax), is the ground. The Earth, the Moon, a satelite and each piece of conductor is ground for antennas. Radial is one of them. Ground must be adequate to kW. Monopole is not directional. Dipole is directional. S* |
