Bob, the best way is drill a hole and sleeve it. Since I run gas line for a
living, I do this all the time.
I have a large Bosch drill that does the job. You can rent these at certain
places for a minimal cost.
Measure the diameter of the group of cables to see what size you need, then
go to the local
plumbing outlet to get some pvc pipe that will take them. Once installed,
seal around the
outside and the inside of the pipe with the cables in there. I use duct
puddy so that I can remove it
later for adding another coax or two. By the way, I think that Bosch has
bits for concrete up to 2"
which will take 1 1/4" pvc pipe. Good luck Steve Narducci W9SN
