My apartment (top floor) has runs of 3/4" (-ish) pex-like tubing (photo attached, Switzerland if it's relevant) running from a central point. One such tube carries an existing coaxial cable (landlord provided, I do not want to detach) from a satellite splitter in my apartment to the roof, where, together with a large number of other such cables it emerges through a (non-removable) metal pipe about 4" in diameter with a 180 degree turn on.
My corona-virus challenge is:
- to somehow thread a cat-6 cable up the same pex-like tubing so as to get internet access on my roof terrace (where the pipe is).
- preferably to do the above with either no new tools or no tools I can't get by mail order.
EDIT: The pex-like tubing is not split (it's solid all the way around).
EDIT: I think I've now gained access to where the pex-like tubes end in the roof void. If I'm correct the cables emerge from many tubes, and are then cable-tied together to a cable frame in the open and go through what looks like some plastered gauze into a roof void, presumably into a pipe the opening of which must be about 15" above the gauze. So there are now two separate tasks: getting the cable up the pex tube (or down it having identified it), and getting it through the gauze and up the pipe (or the other way).
How would you approach the above?
