![]() "John Smith" wrote in message ... OK, if you notice in my post wire length is in quotes, i.e. "wire length." In the example, it is a given that this length resonates at 1/2 wave along with the combined length of the whip (hence, electrical 1/2 wavelength.) So, your post, while presenting individual points and your opinions, in general--seems to answer very little, if any, of the original questions raised--and certainly cannot be accused of containing any specifics. The diameter IS stated (1"), the wire length is the lenght of the wire minus 28 inches which is necessary to be a resonate 1/2 wave, AND this is divided over (1/4 wave at 10 meters - 28 inches.) to arrive at the coil length--the pitch is calculated from the coil length ((1/4 wave @ 10 meters) - 28 inches) and the wire lenght divided by pi (number of turns) spread out over the coil ENTIRE length. And, of course, coil length plus whip length is a 1/4 wave. If you refer back to my original post, you will see all of this IS there... However, critical analysis is a wise beginning of any quest for answers. Regards Roy's answer is right on the mark. The length of the wire is of no help in answering the question. You are confusing mechanical lengths with electrical lengths. Dale W4OP |
