Content preview: Hi Markus, Warren, Stefan, Thanks for the encouragement. My quest for thousands of metres of wire has begun. Stefan's monster coil and Markus' coaxial buckets make me envious. Would it be a good idea to pie wind the wire? G3NYK did some work with pies on LF and got more inductance for a given amount of wire than a solenoid. Perhaps there will be too much shunt capacitance with 3 or 4 pies.

My quest for thousands of metres of wire has begun. Stefan's monster coil and Markus' coaxial buckets make me envious. Would it be a good idea to pie wind the wire? G3NYK did some work with pies on LF and got more inductance for a given amount of wire than a solenoid. Perhaps there will be too much shunt capacitance with 3 or 4 pies. In the mean time, it may be best to follow up on the loop idea. The far end of the 100m wire can be grounded to make it a loop. How much series capacitance will be needed and how does one excite it? An xfmr? 73 Joe VO1NA
