At that frequency, why are you surprised that the current in is different from the current out (in the presence of standing waves)? Heck, I have seen a GDO find the resonant frequency of a resistor with the leads shorted together (that's the entire circuit). Do you think the current is the same everywhere in a resistor that is a 1/2WL loop? -- 73, Cecil, W5DXP |

At that resonant frequency, do you think the current is the same everywhere along the resistor and leads? Remember, you were scornful of such a concept. What I have done is presented a situation where lumped circuit theory totally falls apart as it does in physically large mobile loading coils. That's one reason that distributed network theory was invented. Flat Earth thinking equates to using lumped circuit theory for applications where it simply doesn't work. -- 73, Cecil, W5DXP |

Mark's experience eclipses this nonsense of Flat Earth Socialist rhetoric. Mark hasn't tried a 130 foot dipole on 10m at the same height as his vertical in the direction of one of the four 11 dBi at 7 deg lobes. Even with a perfect ground, his vertical tops out at about 5 dBi, a full s-unit below the dipole's best lobes. Flat Earth thinking equates to asserting that a vertical monopole will beat a +11 dBi beam (or lobe). -- 73, Cecil, W5DXP |
