For LF use you could probably increase coupling caps and use a bigger loop, and change the input LPF

This is the one members of our club (IVARC) have been making as a club project.   19 have been made, all on a custom SMT PCB as an exercise in SMT construction as well as members having an RX loop for noise reduction at HF   (And no, PCBs are not available outside club membership)

Hello LF'ers

I  am having no luck with my mini whip antenna, for whatever reason it
seems very deaf, so was wondering if I can home brew something like the
magic  box  of  tricks for the (expensive IMHO) Wellbrook Active Large
Aperture Loop Antenna shown here:

https://www.wellbrook.uk.com/loopantennas/Loop_Antennas/ALA100LN

Anyone  know  of  anything  that  is  similar  and documented for home
construction please?
