[TowerTalk] Pull rope in PVC

[kb9yku]

the miles of conduit i installed  and pulled wire into
i have found it better to remove the old  wire pull it back in with 
the  new wire
unless  you  use a new conduit
put 2  runs of conduit   in ware you need one now

2 in  conduit  mite help with a  small fill
like wire that would  fit in a 1/2 in. in the two inch
they make liners  to  help you add  more wire later  its 
used  in  underground ducks
its  polyethylene  i think  and you pull them all in at one time with a 
light pull  string  in it  to  pull  rape in with
