Reasons to use concrete troughs vs buried PVC pipe:
* Accessability to any area of the run from above.
* Air circulation eliminates most of the moisture issues.
* Pop the tops to lay a new run or eliminate an old run with no problems
with coax or
   fish line tangles.
* Probably nicer for hardline runs than trying to get it thru PVC.

Don't have a need for it here but like the idea.

Maybe I'm missing something, but what's wrong with PVC pipes with drainage
holes? Is there some advantage to using concrete (or similar) troughs with
covers?  Jerry K3BZ

Mel:

     Try Trenwa (it's spelled correctly as shown and I don't have a URL).
My former employer, an electric utility company, used to use Trenwa precast
concrete trench products in routing electrical control cables underground
through our power substation yards.  As I recall, the pieces are essentially
side walls and square u-shaped supports for the ends of the lids.  The
cables are merely laid in the open trenches, then the covers are put into
place.  Trenwa even made this stuff out of flyash so it was significantly
lighter than concrete.  Also made lids that could be driven over.
