Cecil, you have two stubs and they are driven antiphase (typical of a doublet) and through symmetry would have equal antiphase currents when compared to their opposites, but not necessarily equal currents within their twin-pair of lines. The sum of ALL currents (and not just the myopic view of one of two stubs) would suggest exactly what Roy has offered. Sorry, Richard, 1/2 of the loaded dipole turned vertical doesn't show a trace of horizontal radiation. Sorry about that. Roy suggested the stubs might be radiating. EZNEC says they are not. You can add two inches of vertical wire to the ends of the antenna and see the red vertical radiation. The stubs are 0.04WL, #14 wire, and 6 inch spacing. How much could they radiate on 75m? The difference in current is not due to radiation. It is due to the phase shift between Ifwd and Iref through the stub. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
