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.=C2=A0 = =C2=A019 have been made, all on a custom SMT PCB as an exercise in SMT cons= truction as well as members having an RX loop for noise reduction at HF=C2= =A0 =C2=A0(And no, PCBs are not available outside club membership)

Hello LF'ers

I=C2=A0 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=C2=A0 box=C2=A0 of=C2=A0 tricks for the (expensive IMHO) Wellbrook Ac= tive Large
Aperture Loop Antenna shown here:

https://www.wellbrook.uk.com/lo= opantennas/Loop_Antennas/ALA100LN

Anyone=C2=A0 know=C2=A0 of=C2=A0 anything=C2=A0 that=C2=A0 is=C2=A0 similar= =C2=A0 and documented for home
construction please?
