As well as tv lopt transformers try mains toroidal wound transformers.
I have just tried a large one with a secondary winding giving me 116 mH just about what I need to resonate my antenna. I cannot detect any noticeable loss
at present on RX, in fact it enhances the signal.
It will depend on core material whether it is suitable or not, no doubt there are several varities.
