I am getting close to pulling some cable through a 1 1/4 inch PVC
conduit that runs about 20 feet from the third floor attic to the
basement. The contractor claims the conduit is a "straight shot" with no
bends. I have three LMR240 cables with PL259 connectors on each end. And
I would also like to pull a 450 ohm length of ladder line. (Measures
about 1 inch.) And I would like to pull at least two 16 gage insulated
control wires.

I specified a similar PVC conduit when our home was built. I simply
"dropped" the cables down the conduit from the attic, and let gravity do
all the work. If you drop them all down together at the same time you
should have no problems. The LMR240 and control wires will be fine, but
ladder line in the same conduit with all those other wires probably
won't work very well.
