I'm planning to run Cat 5 and telephone cable underground to an outbuilding to extend the phone and the PC from the house connections. I'll be putting the cables in a blue polypropelene water-type pipe to protect them.
Please does anyone know if I need any special specification cable for the Cat 5 and telephone cable if it is going outdoors?
You could always lay it so that both cables can be easily replaced, if they are lose you can just tie new cable to old and pull it through. If you want proper outdoor cat 5e scroll down here click here
