There is a very small slice that amateur radio gets in this band, in theory it would be nice to have a bigger slice, but honestly, building antennas for this band to transmit anything worthwhile would be pretty hard.

My 7 Mhz antenna (HF, 40m band) is 67 feet long, and goes across by whole house.

The smallest antenna you could get away with for LF would be hundreds to thousands of feet long.

You might be able to go smaller if you enjoy suffering. Though, there are some pretty creative antenna designs that defy logic.

Does stapling it to your neighbours' fence lines and painting it like the wood count as creative?

I wonder if you can couple to your local distribution grid, and not get arrested.
