Roy sarcastically referred to "Yuri`s Cosine law". Yuri is right. Current into the bottom of the coil is 0.924 A, and into the top of the coil it is 0.383 A. Roy disappeared from the argument. Yuri seems to have tired of the dispute too. Yuri is not really tired of the dispute, more like he has found enough support for what he was looking for. There are still those who do not believe that current can be different at the ends of a loading coil, there are those who now see that maybe "she's not flat", and then those, who new it all along - what's a big deal. The main confirmation that I am not a F0OL (as certain guru(s) tried to imply) has been achieved, thanks to Cecil and others I have understood the mechanism of the phenomena. I have enough ammunition to do some of my own testing and measurements and as I promised to write it up with other fellow believers, 'splain it, provide facts and outline importance for the loaded antenna design. Hopefully the modeling software will be able to capture and use it properly for better results and understanding. And yes Virginia, it is VERY important for the modeling. If the radiator models no change in current accorss the coil, but there is more like 40 - 60% reduction, THAT is important, because it will throw the whole model off if you add more loaded elements like in parasitic arrays. Right now I am very busy organizing Christmas Concert in NYC/NJ area (www.computeradio.us) by 80 member Ukrainian Ensembles from Toronto. Anyone in vicinity is cordially invited to get in tune with Christmas spirit, away from the shopping fever. It is something to see, like small Mormon's Tabernacle Choir. I managed to play with new TenTec Orion rig in CQ WW and I am also working on writing "contesters" review of the rig. Quite a performance but how "cheap" for $3.6k radio. So, I follow the "coil thing", I just run out of arguments, I want to do my experiments and then put it together in a comprehensive article. So thanks to all pros and cons, I got what I needed and this group is the best! W8JI is WR0NG and one should take his "wisdom" with a grain of salt. His web page has more stuff that is off.
