[Towertalk] Coax conduit

[David]

Getting ready to dig the concrete base for my new tower and plan to run a 1
1/2 inch PVC pipe from my shack about 30' away and up through the concrete
base.  This pipe is big enough to carry several coax lines plus the rotor
cable, so is there any reason I would want to run a separate pipe for
anything else?   The reason I ask is because I see photos of a ham
installing a tower on the texas towers website and he has two PVC conduits
coming up through his concrete base.
