[TowerTalk] TowerTalk Conduit Burial

[Dave - W3NP]

When employed with a major railroad as a communications tech and also 
for my ham radio installations. I always glued and buried the conduit 
first. Then tied a pull string to a shop rag and used a shop vac to suck 
the pull string through. Much neater and cleaner method and ensures that 
when/if you have to pull another cable through or replace one, that it 
will be doable.

73, Dave - W3NP
