10 - 100 HZ freq. range

[Beginner19]

Good day !

If i want to pickup frequency range from 10 - 100 HZ, what kind of antenna do i have to build ? ( im using isolated copper wire (0.5)).

I need just antenna design, for now ....

Basicly, let me put it this way. If you have source, which is emmiting this freq. range, how to pick up this freq ?

Thank you !

The antenna size will be at least a quater wave length. wavelength = velocity of light/frequency.

An inductive loop antenna will have an resonance of 100Hz (That implies a very big inductance ; and therefore many thousands of windings

 

[Beginner19]

So, if the 100 Hertz has a wavelength of 3e+6 meters, total amount of antenna should be 729. Is this correct ?

If i use big diametar (some 5 cm pipe) can i use double or triple or more windings, on 1 metar pipe length to get this work ?

Any idea... someone ? :?

Magnetic antenna ? Could be an idea; take idea from the ferrite antennas used on LF radios.

Where can i find such antenna ?.
Can i make my own ?
