I'm trying to pull rg-11 through 3" conduit with a fiber line already in the pipe. The fiber is in it's own orange 1" pipe inside the 3". It's a 155 ft run with 2 90's and 2 45"s. I tried running my tape through, but kept getting hung up aboout 120 foot in. On each end. I tried sucking a bag through, as I thought that didn't work. I also tried putting a new "flexible" end on my tape, but still can't get through. Does anyone have any advice or pointers that might help me complete this task? Thanks
