ULF antennas

i've been considering an antenna for the audio frequency range plus 1 to 20
hz. basically a big coil would work.

i've thought about using a steel drum, but i don't have room for that in my
new QTH. mu metal rods would be very expensive, even ferrite would be
expensive for an 100,000 turn antenna.

not sure what to use. maybe steel core.
