One of the things I am trying to find out is how one can calculate the loop inductance of a big transmitting loop (based on the dimensions). I found 2 formulas for the calculation of a 1 turn coil, but both mention the dimensions in cm, so I don't know if they are usable for big loops. I have 2 questions : 1. Does someone has a formula that has proven to be usable for big loops. 2. To all (ex-)loop users : in case you ever determined the inductance of your loop I would appreciate it if you could let me know the inductance and dimension of your loop(s). A nice easter weekend (with a lot of chocolate eggs) to all, 73 Rik ON7YD
