Re: Newbie about to run Cat5

["haweste" <haweste@xxxxxxx>]

Daniel,

Thanks, that's good - all my hidden runs will be straight. For now
I'm just installing conduit and will pull the cables later.

I'll screw it to the wall as you suggest and also see if I can find
out more about the tape (I'm going to do the plastering).

Good news about (no) interference. Not all of the speaker (or Cat5)
cables wil be live all the time and it's obviously easier to run it
all in the same conduit if I can.

Thanks again,

Tim.
