I have my cable from my satellite dish enclosed in 1 1/2" pvc under my sidewalk. Now I would like to install 3 post lights along the same sidewalk and would like to run the electrical wire in the same pvc. Is there an electrical wire that won't disrupt or interfere with my satellite cable signal? Maybe some type of shielded wire.

No, cannot mix power with communications wiring in the same raceway.

Code generally does not allow CATV cable and electric light/power conductors in the same raceway. There are exceptions, but with your current setup, it cannot be done.

Thanks Guys,

I'm glad I asked.
