Post Running coax underground ?
Toying with the idea off running around 30 feet off coax underground from mast to shack window . Be great to hear from anyone here who has done such a thing and how you went about it ? The area where the coax would be buried would be mostly under grass. Would be using rg58x coax cable which although thin would be enclosed within tubing. Thinking off using this to enclose the cable within... any thoughts ?

Garden hose is another option.

Post Re: Running coax underground ?
I run a short length which i wrap fully in good self amalgamating tape. It ends up like a submarine cable but its never failed me in many years service. I looked at garden hose etc which isnfine if it stays dry, but i couldnt fathom whatto do if it didnt...

Okay cheers guys as always appreciate the advice given. Never thought about garden hose so yes another idea !
Maybe over thinking things but not sure regards how deep down to lay any coax / hose so that frost is not an issue come winter time ? Great idea re. Self amalgamating David do you use rg58 or rg213 ?

I used rg58 for my run. What aerial are you feeding? Only ask because if you can use airborne open wire it would be better

I just use drainage duct, the plastic variety as there's no vehicles going over it.
Loads of cables and just lift the lids to make changes.

It goes along the edge of the lawn and crosses a path, then along the edge of the drive to the house.

Just make openings in the bottom so it drains down its length, rather than fill up with water. :lol:

Cheers

Tony

Narrow width drain pipe with glued joints end caps at both ends,
depending on length you could run two lengths of string/rope through
so you can add more coax runs in the future.

Post Re: Running coax underground ?
:) It depends on how long a run as cost might impact on your decision

If it is going into a flower border I would use 15mm copper pipe as conduit (seriously) that way it can't be easily cut with a spade by accident .

I remember many years ago I had a friend that lived in a village near here called Ettington and he did something similar.

Where the cable goes in and comes out you can use a compression joint with an end cap. If you then drill the end cap to the some diametre as the coax you can seal it with either silicon or hot glue at that point.

I hope that helps in some way

your local plumbers merchant will sell barrier pipe, 10/15/22/28mm diameter, and 25/50m lengths, grey or white.

Rg8x in hose pipe. Worked perfectly until family decided to fix our garden one day. Lawn edging shears can cut through those pipe in 27 separate locations :banghead:

Motto is just cos you know what it is.....

If buried underground and for a single run of coax my choice would be housing it inside alkathene pipe.
