(from the website) If you find that you are getting unwanted noise (buzzing, popping, whining), run your radio power leads straight to one of the vehicles batteries. This will by-pass all of the other circuits that could cause unwanted interference. Enough said on radios. Well, it starts out well, at least. Certainly everyone here that has hooked up a rig in the car found that direct connection to the battery solved all their problems. I think someone forgot to tell Ford. -- 73 for now Buck N4PGW |

Hey, can someone take the time to do a brief critique of said article? It might be good to for interested parties to verify their knowledge. For example, I note: - The notion that "CB antennas" require a ground plane. My understanding is that some antenna designs include one or more counterpoise elements, but that this is different than a ground plane. - Suggesting that the ground plane is necessary to pick up ground waves. - Suggesting the ground plane is part of the feedline. If the groundplane is a counterpoise (as suggested in the first paragraph) why is the feedline part of the antenna? Is this some sort of special feedline they are referring to? - Frequency changes due to changes in the electrical length of the feedline. Again, unless the feedline really is part of the antenna, isn't it the idea to have a theoretical perfect feedline can be nearly any length? That is, from the point of view of the radio equipment, the feedline has infinite impedance? (I'm fuzzy on this one, so remind me gently if I'm misleading myself.) - The discussion of SWR is so wrong it has caused me to forget what it really is. Sorry. - The section on tuning somehow conflates the location of the antenna with it's electrical length. I invite everyone to set me straight, and in the process offer a good rebuttal of this article. |

Wow, I didn't know that aluminium doesn't make a good ground plane! I quess all of those aluminium chassis are just no good! I especially liked the SWR explanation. I'm going to use it when next I teach an Extra class. R |

The manufacturer didn't include the matching coax. -- 73 for now Buck N4PGW |

I'm afraid I don't get your meaning. Some might say that your semiotics is obscuring your semantics. Not that I would, of course. |
