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.
