Coils and Transmission Lines.

What's next? There is less current in a wire (coil) where wire (coil) gets hotter? Let the games begin! Thermometers don't lie, meters don't lie, even EZNEC shows it! So wasaaaaap? If you're looking for an argument, you're looking in the wrong place. Nobody denies the raw evidence, like the fact that some loading coils get hotter at the bottom than at the top... and the fact that some other coils don't (or nowhere near as much). There are good explanations for everything you see. But the only valid explanations are the ones that account for *all* the facts about *all* types of loading coils. The argument is specifically about Cecil's attempts to explain the evidence, using his own particular ideas about "standing wave antennas". He makes it kinda work for the cases he wants to think about, but in other cases it gets things fundamentally wrong - and that isn't good enough. -- 73 from Ian GM3SEK 'In Practice' columnist for RadCom (RSGB) http://www.ifwtech.co.uk/g3sek |
