Hi

Keep in mind that you are not allowed to broadcast on 60 KHz. 
You can generate a signal there. If you do, it very much needs
to be constrained in terms of how far it goes. With a small antenna,
it is not going to radiate very far. Coupling into things like power
lines ….. who knows. Either way, if it gets off your property, that
really isn’t something that should be happening.
