![]() TRABEM wrote in message ... I think you are heading down the wrong path with the series circuit as your fighting a loosing battle. Assuming a perfect coil and capacitor you create an infinite Q circuit. Now you hook it up in your circuit. First there has to be enough resistance to develop the voltage , and here is the rub, as you increase the resistance to develop a voltage you decrease the Q. Yuk! Go with a parallel circuit like the rest of the world uses and you will be going in the right direction. I think I'm starting to get it. Am I cutting off my foot to spite my face:: Comments made by you and a few others have nudged mein the right direction..... The higher I make the series resonant Q, the lower the impedance goes, hence it's almost impossible to get a lot of voltage out of it?? Not sure why it matters that much. But, I was under the impression that a perfectly matched antenna and front end would only decrease the Q by a factor of 2. Follow along with Richard's comments if you like and add your comments as I check here often and read everything, sometimes many mant y times:: Regards, T PS:I had begun thinking that the higher imedance presented by a parallel loop was harder to match with a balun, which is why I started thinking of a series loop. I'm gettin there, thansk again. ======================================= Trabem, This discussion is getting you nowhere very fast. So let's summarise. I don't have your exact dimensions but the following are good enough. L = 27uH, Reactance = j10 ohms, Conductor loss = 0.05 ohms, ESR = 0.01 ohms, Radiation ohms = 0. Receiver input = 10 ohms, Ground loss ohms = 0.01 The intrinsic Q of the loop is 10 / 0.05 = 200. The working Q of the loop, when series connected, is Reactance divided by the SUM of all resistances including the receiver. Working Q = Reactance / ( 0.05 + 0.01 + 10 + .01 ) = 10 / 10.07 = 0.993 Take note of the ridiculous low value of working Q due to the loop being in series with the receiver. ---- Reg. |
