"Dave Platt" wrote to us It started when the dummyload was too small for a job. It's for 40 mtrs. But making it is barely possible. It should have a Zo of 50 ohms ? And what about the Q factor ? Looking on my swr meter it gets better when i put my hands near it and at a very small C rate but still in the red. Anyone ? A "pure" LC circuit is lossless... both the L and the C are pure reactances, and neither will (or can) dissipate any power. Not dissipate but surely radiate in a closed box! In practice, you could make an LC series circuit which would be 50 ohms resistive at a single frequency... Yes, it's for a single frequency. Since an antenne is also a LC-circuit that doesn't get warm but radiates in fields. I had it all open built so i suspect mantelwaves etc. But on paper a series LC circuit forms a loading of a particular Zo. This statement is still right? Lets say an input on a semiconductor p.a. stage with an LC series circuit.. |
