Ok, Im not really repairing anything (yet), but since I love this
group so much, Im posting this noob question here anyway.
Im in urgent need to connect an adsl access point to the telephon
line and to do it I've two options
The 1st one to use about 1 meter of telephon cable and have it
sharing the same plastic duct used by the power grid wires (not the
smartest idea, I know).
While the second one is to connect the access point through a 6-7
meters cable enclosed into a 5 to 6 meters copper pipe (not grounded)
Could this pipe work like an antenna and represent a possible source
of noise on the signal cable? or could the cable lenght cause an
appreciable signal attenuation?
Which of these 2 options should I pick?

#2 is best. the copper pipe will act as a shield and is harmless.


You should never run signal wiring parallel to service power wiring. The
additional 6-7 meter length of wiring will have little effect on your ADSL
signal. The wiring back to the phone company's central office is much
longer. The copper pipe will have no effect, other than physically
protecting the wiring from damage by insects and rodents. If you experience
interference of any sort, you can connect one end of the copper pipe to
earth ground (either directly to earth or to a power line safety earth
connection point. Chances are that you'll never know that it's there.
