--- on the heady topic of " HIGH Q CAPS FOR VLF LOOP ANTENNA?" TR From: TRABEM TR Xref: core-easynews rec.radio.amateur.antenna:219360 This should require a matching transformer otherwise not enough current can flow to take advantage of the potentially huge Q. Without current flow there will be no energy storage in a series circuit. In a parallel circuit the current flow is internal between the parallel reactances but in a series circuit it must be external. A series circuit is naturally current driven so the transformer would basically be converting current into a voltage that the receiver input can use. If you measure your loop with a test signal you should find it requires a lot of current and little voltage. From your investigations, calculate the effective resistance and use this as your Rs to find the actual Q and the matching turns ratio required for an autotransformer, for example. Good luck, A*s*i*m*o*v .... Why is Brassiere singular and Panties plural??? |
