I have a 210ft run of 4 in smooth bore plastic cable duct going in a
straight line 3ft underground from outside my shack to a small shed at
the base of my tower. There is a brick-built man hole (aka inspection
chamber?) 3ft x 2ft 6in at each end.
Presently I have LDF2-50A in the duct but it's a tad lossy and I have
the option of some LDF4-50A or LDF5-50A coax.
I have a draw rope running through the duct and a pulley set into the
floor of the man hole each end just outside the duct opening but I am
wondering how easy it is doing to be to pull either of these thicker and
heavier cables into the duct?
How do you guys at big stations do it? Will 3/8" polypropylene draw rope
and a strong young man (ie not me!) be able to do the job, or are we
looking at steel wire rope and a power winch?
Thanks,
Alan G3XAQ
