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.

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.

Just don't connect the copper pipe at two different points to things
that are not at exactly the same potential..Otherwise, you will have
current flowing in the copper pipe and that can introduce noise into
the telephone cable. Even if it is two twisted pairs, there is a
common-mode current induced in the telephone cable that might do
interesting things to whatever is connected at the ends.

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.
