And if any of the copper is carrying digital data, square waves are hugely rich in harmonics well up into the MHz bands, and would therefore tend to radiate better from any above-ground wires between poles, possibly even roadside pedestals.
Note that the copper in your Cat 5 Ethernet cable is treated as a transmission line. It is correctly terminated at both ends, so there is very little RF radiation. If there were a lot of RF, it would interfere with things like TV, cell phones etc. Cheers - Bill ------------------------------------------------------------------------- Bill Frantz | Due process for all | Periwinkle -- Consulting (408)356-8506 | used to be the | 16345 Englewood Ave. frantz@pwpconsult.com | American way. | Los Gatos, CA 95032, USA
