All that's required is di/dt and some radiation resistance. A simple
loop antenna will do. Get a 1 foot diameter loop wire and place a
signal generator on it. The idea is just to generate some current.
Although you'll be hard pressed to get the generator down to those
frequencies. :-) Therefore you'll need to hook the loop antenna to a
d/a converter & amp board controlled by your pc computer. A simple
program can generate any frequency you want. I don't think the
computer life span is long enough.

Better yet, get a permanent magnet and slowly turn it. Perhaps use an
astrononmy telescope motor. The idea is to slowly rotate the magnet.
If the magnet rotates in 1 cycle every year then that would be
3.170979198E-008 Hz.

Perhaps we can look in the universe and find even lower frequencies.
How about our sun, which generates a magnetic field, rotating around
the galaxy?
