Hey @Squishman, can you feed the cable down the middle of the pipe without it contacting any screws or rough edges? Then you can seal off the top with a "domed" blob of outdoor silicone to prevent water ingress. That way the cable is better protected, and it won't "rattle" in the wind. I did that on a 12 foot mast at our Cabin last summer for a Cell Phone Antenna. Worked great! ;)\n\nDue to the fact that there are screws in the pipes, I'd say no. If I remove them, then there are burrs of course.
