Default Pulling Cable in Conduit



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.

Any advice would be appreciated.



I think you can get those three coax lines down the straight conduit
if you stagger the PL-259 connectors, however, once you have a couple
cables in the conduit, you may find there isn't enough room for a PL-259
to squeeze by, so you may need to remove the connectors, pull the cables
and then reinstall them. Three LMR240s and two control cables are going
to fill that conduit more than you realize!

As far as the Ladder line goes, DON'T ! It will be nearly useless
packed in with all that coax and wire as it needs several inches of
SPACE around it to function properly, with no nearby metal objects. That
coax braid in close proximity will drastically reduce its effectiveness.
