Apparatus and method utilizing a transmission medium with a plurality of hollow pathways

A launcher, comprising:

• a processing system including a processor;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
• receiving communication signals conveying data;
• and
• generating, according to the communication signals, a plurality of electromagnetic waves that propagates along a plurality of hollow waveguides formed between portions of outer surfaces of a plurality of insulated cables, wherein each hollow waveguide of the plurality of hollow waveguides facilitates propagation of a respective electromagnetic wave of the plurality of electromagnetic waves, and wherein the plurality of electromagnetic waves propagates without requiring an electrical return path.
