Hi Richard,
I thank you for posting such revealing evaluation of my deficient, misleading knowledge. Yes, my web site is full of old no good stuff. Even my C6AYB picture is too many pounds old. Anyone with spec of antenna knowledge can see that "G5RV" is operated as dipole, judging by the standing wave current distribution, and it is not cardinal sin to call it G5RV dipole or vice versa. If I can get away from deflecting mumbo-jumbo and over holidays, I will start working on the project. Looks like audience here is looking for sticking needles rather than providing answers and suggestions to questions. The main thrust of question posted here was, should he stay with loading stubs or do something better. I described what was done, and stubs suck, coils are MUCH better and that current distribution is what it is and illustrated in that "butchered" drawing by W5DXP. I humbly bow in view of your much better, educational posting. I am sure the questioner is fully satisfied with your answers and solutions.

Have look at the end of my article http://www.k3bu.us/loadingcoils.htm Hi Yuri, As usual, your statement has nothing to do with your link. What is worse, this EZNEC model is from a third party who is not available to comment as to the accuracy of your statements about performance. Even more is the compounding of error at the link: "G5RV antenna using inductors in the form of loading stubs" Clearly, then, it is NOT a G5RV. When we continue with the commentary we find: "When simple inductance in Eznec is inserted in place of the stubs, the current erroneously is shown as the same at the both ends of the inductor." Clearly, then, the model designer who expected something other does not know how to design the model. It would seem after several years of corrections to this error you continue to publish, that you would have updated your page by now. It is easy to offer broken solutions. This group sees many of them that are then used to discredit either the tool or the theory. What these broken models reveals are the bankrupt designer. Perhaps you should vet the material from your contributors more closely. 73's Richard Clark, KB7QHC |
