![]() "Owen Duffy" wrote Of course, implementations will have slight differences in actual feedpoint impedances, and the outcome is very sensitive to slight differences in feedpoint Z. This "no-tuner" matching scheme will probably need significant customisation for each implementation. ========================================== The World-famous G5RV. --------------------------------- What everyone appears to forget, is that Zo of the balanced twin-line section, on all bands except at 14.15 MHz, has a considerable affect on feedpoint impedances, swr, losses, etc. When describing systems and performance nobody ever mentions what Zo of the feedline actually is. Omission of Zo reduces any following discussion to blythe, innocent nonsense. R.L.Varney himself never gave a value to Zo. He didn't need to. He was concerned mainly with 14.15 MHz. It would be unfair to accuse him of not understanding the serious effects of Zo on other bands. ---- Reg. |
