I'm designing a sonic pest deterrant, with a signal generator generating a signal of around 30kHz, which is then transported to speakers (and amplifier if necessary.) The whole system will be outside, hence subject 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 conclusive.
