And, since there's more dielectric in coax than in TP, there's more loss. And, since copper losses are greater than in TP due to the much smaller center conductor, there's more loss.
The loss at higher frequencies has nothing to do with the amount of copper. Because of the "skin effect" lots of smaller wires will have less attenuation than a thicker solid core. Only when pushing many amps through a wire (as if hf-transmitters) this might be an issue, although even then, isolation of the dielectricum is more of a problem. Pushing 1kw through RG58U gives a nasty smell. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
