No probs. please take time as no rush.
But how do you measure inductance of the loop element?
What meter do you need for the measurement?

I feel that active antennas must be in good specs. and good quality ones, because it they are not, they could bring problems with intermodulation, cross modulation and overload problems especially to the cheap receivers with ultra sensitive front ends, which are designed to run on builtin whip antennas, or very short wire antennas.
