Can I run the high speed internet cable in the same conduit/pipe as the cable TV...

...line? We have a high speed cable line running from the telephone pole underground to our house. We want to get cable TV, but the cable TV line stops at the telephone pole, so we're going to have to run the cable TV line underground ourselves. We know there is enough room in the existing underground conduit to house both the high speed line and the cable TV line. Can we run both together in the same conduit, or will there be interference and problems as a result?

No problem at all. Go right ahead.

It shouldn't be a problem. I'm a contractor and we do it regularly.
