Too loose coupling is always better than too tight even if some performance
is given up.

>>Your secondary should be at least 1 inch above the primary -- not below.
>>below the coil will be overcoupled and you will be splitting your energy

>>Checking the coeff. of coupling is detailed in the Tesla Archives section.
