[UK-CONTEST] Antenna cables underground.

[Roger Cooke]

Hi John.

  My experience with this has been dire! If you only want to do the job once
and you have the amount of cables ready that you wish to feed through, then 
that is fine. You can then feed ALL the cables simultaneously through one 
section of pipe at a time, join them up and then bury them all in one. 
It also depends on how far you wish to go, and how many bends you might have.
   My findings were based on just thinking it would be easy to feed a cable through
a 3 inch pipe, hauled through with a pull-rope, attaching another pull-rope to the
cable to enable me to pull the next one through etc. The run was long, about 80ft
from the tower to the house, with a bend at the bottom of the tower ( to keep the 
water out ) and a bend where the pipe accessed the house. The first two were fine, and then it got difficult. The pull-rope cork-screwed around the cables that
were already in the pipe, and by the time I had four cables installed that was it,
I could not pull any more through. 
  Since moving, I use a catenary wire and drop the cables from that as support,
much easier to do! 
  I suppose it would have been easier with an 18inch pipe!
