I'm designing a sonic pest deterrant, with a signal generator generating a 
signal of around 30kHz, which is then transported to speakers (and

to all weather conditions, and the speakers will be up to a few hundred 
metres away from the signal generator. What is the 'best' method of getting 
the signal from the generator to the speaker? I've tried looking into 
ordinary wires, microwaves, IR, laser, etc, but the data has not proved
