Second what Mike state in his response.
I've found, from hind sight as Mike said, the best method is to get as many cables through the PVC with the initial "pull". Also, remember to attach a "traveller" to the front of the cables to allow the pull rope to be retrieved through the pipe. Keep the cables and the traveller line going into the pipe as parallel as possible. You want to keep the traveller from wrapping around the cables. Getting the traveller and the cables to stay parallel with each other may be impossible, but try to minimize the traveller line getting wraped around the cables.
The large PVC pipe will make the next pull of cable(s) much easier even if the traveller line does get wrapped around the initial set of cables.
A four inch PVC pipe is run from the house to the base of the tower (~60 ft) at K4GMH. Using the above technique three "pulls" were used to get two FSJ-4 coax cables, and control cables made of out of 14 gauge NM for the following: two stack match pluses (six wires each), two antenna selection switches (four wires each), two rotators (six wires each); plus the two, sixteen wire control cables for two, 4 element SteppIRs. The majority of the cables came through the pipe during the initial pull. The two other pulls were made without any problem. By using a traveller line the pull rope is still in place ready for the next inevitable cable(s) that will go through the pipe.
