1. An apparatus, comprising:
a guided surface wave receive structure configured to obtain electrical energy from a guided surface wave traveling along a terrestrial medium;
an electrical load coupled to the guided surface wave receive structure, the electrical load being experienced as a load at an excitation source coupled to a guided surface waveguide probe generating the guided surface wave;
processing circuitry that identifies at least one frequency from a plurality of available frequencies associated with a transmission of the guided surface wave traveling along the terrestrial medium; and
processing circuitry that adjusts a frequency at which the guided surface wave receive structure receives the transmission to the at least one frequency via the terrestrial medium.
