Zs can certainly affect the impedance looking back into the feedline. I did that, and the SWR did not change. But, then you could say this was by definition because the meter measured RL/Z0. Chipman alludes to the problem not occurring with a resistive load or with lossless lines. If the load is 50+j500 and the impedance looking back into the lossy line is 50-j500, this seems to be the correct conditions to cause the localized resonant energy transfer problem. -- 73, Cecil, W5DXP |
