[OKDXA] Advice on placing coax in plastic pipe

Makes no difference at all... It just seems wrong to run electrical 
conductors in a wet location but as a former strap hanger I can 
guarantee you there are hundreds of miles of wet cables in subways and 
sewers under the larger cities of the east coast. Subterranean real 
estate is too limited not to multitask those tunnels and water happens.

I like the idea of some sort of conduit as it's SOP for me to get a 
bigger & better idea shortly after completing a project and if I ever 
need to re-pull the cable that beats the pants out of a direct burial 
install. The only catch to perforated pipe might be silt working its way 
into the pipe over time making a re-pull difficult or some bizarre 
chemical reaction with salts or minerals in the soil. The latter is a 
real long shot as PVC is fairly non-reactive and if it did would likely 
be a slow process. If I lived in upstate PA where sulfur creeks are 
common I might think otherwise, but there could be an advantage to damp 
coax below ground in terms of choking common mode RF on the shield or 
lightning protection. Better to dissipate a direct hit by smoking the 
coax before Thor gets near the shack.

Slightly off-topic thot:  If a telco / cable company runs fiber optic 
through plastic pipe, how does someone with a metal detector find the 
run before the backhoe arrives? Yeah, I know, look for the splice boxes 
about 500' apart. The cable runs between 'em. Usually.
