[Urgent] Interferences

[Xon]

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.

Absolutely absolutely do not do this. Not even "not the smartest..."
it is totally stupid, from all viewpoints and is not an option.

Since this is the only option you have, go for it. I doubt the copper
conduit (I will have to assume it is only going to be used for this
wire) won't affect it substantially.

What kind of signal? What kind of wire? What you don't say is vital,
either tell people exactly what you are doing, or forget getting
meaningful answers.

There is only one option above.

Don't share the DSL wire space with power wires. Make sure you twist the
pares if using raw wire or use CAT5 and one of the the twisted pairs.
That extra few meters isn't going to affect your line quality of noise
level.
