First off, nylon will stretch. Greenlee and other electrical mfgs. sell
buckets of poly rope specifically for this purpose.
I've done several 300'+ runs using a shop vac. Connect the shop vac to one end
of the run. Tie a plastic bag or bunch up some PE sheet and tie that to your
pull string. Shove the plastic bag into the other end of the run and it will
be sucked into the shop vac.
This method has never failed to work for me.

Subject: [TowerTalk] Pull Rope in Conduits?
I'm about to place a number of 150' Sched 40 PVC conduits between my shack
and new tower. I want to end up with small 200 lb. stength nylon twine in
each conduit, then use that small twine to pull through a larger 1/4" nylon
rope for the actual cable pulls.
Should I use a fish tape to pull through the small twine as I glue on each
additional section of conduit? I'm concerned about the PVC cement sticking
to the nylon twine. Or is there an easy way to install the small twine
after a whole 150' run of conduit is completely glued together?
73,
