For what it's worth, I too concur with the over-engineering - perhaps it
is just the latent EE in my trying to escape ...

I have used LMR400 DB inside a 4" pvc conduit, I have both installed
the runs in the conduit as I built it and I've used nylon drawcord. BTW
that new silicon survival tape makes a great way of temporarily "bonding"
the cord to the coax.

For me, I use Times compression UHF connectors -- available from Tessco.

This is a tad more expensive, but i've never had failure -- aside from a mole/
chipmunk that broke into the buried conduit and chewed the coax -- I could
tell the little rascal by his perm perm ... hi hi

Good luck Milt & please let us know how the project turns out.

RG-8/u or RG8X ??? 20 ft with no bends is easy, but add a couple 90 degree bends and double the distance ... it's a whole ball game !

Been pulling lots of big cables through conduit for many years. Coax can present different problems especially if one has to pull connectors from a pre-made coax. Lots of years of working n tower/antenna projects everything from 50 ft. to 190 ft. . One thing I've learned is to always over-engineer things and to be prepared for unexpected.

Just saying that every situation is different and sometimes what looks easy, isn't.

I pushed rg8 through 1.5" conduit 20ft with 2 fingers, but then I left it elevated to clear the mower along a wood fence. Would not recommend for the world above 50. but fine for HF.

I would recommend the Conduit. Go at least twice as big as you think you

need. when you put it in, put in runs of good nylon sting from one end of

the conduit to the other, and just leave them there. As long as they don�t

get tangled, you can pull more runs through later on. Much easier than

digging a trench each time you want to add a run of coax.

Subject: [070] RG8 Co-ax that can be buried?

Guys/Gals,

A bit of technical help please?

Does anyone know of a quality RG8 co-ax that can be buried? I have about a

30' run that goes to my tower. It either has to be buried 4" to 6" under the

lawn, or sleved in 4" pvc pipe with weather heads on each end.

The labor is a big difference for me. (And my gardener)

Looking down the road a bit, it's a huge hassle to do the pvc pipe since the

addition of antenna's to my tower would require a 'fish tape' or strong cord

in the tubing to pull additional co-ax runs through.

Experienced help pls?

Milt.
