I ran into this when trying to run the wires up the existing conduit in the mast. I was able to slowly push the obstructions further up the mast with some pressure on the snake. However, it eventually wouldn't budget further.?Unfortunately, I had to run the wires outside the conduit. I used the old 'zip-tie' trick to try to keep wires from slapping. A couple of weeks in, seems to be working.?
How far up is the obstruction? If it's not too far, you might be able to get a hold of some sort of rod or pole and poke through as Rick is suggesting.?
