Underground Coax cable run help.

[avatar7]

Hi,

I am looking to run some coax underground that will eventually feed to my garage to I can install a motorised dish. I will be digging up a strip of my turf so I can lay the coax under there.

Is there any suitable trunking/conduit I can use so it is shielded from frost and damp that people have used form past experience? I was thinking some sort of coiled barrier pipe.

Thanks

I just buried it under the ground put the spade in lifted the turf a little and tucked it under about 3 or 4 inches, just moved down the garden doing that. I was going to thread it through an old hosepipe but in the end I just went for it and it's been in there a few years now with no loss signal through 2 pretty serious winters. You can over think these things plastic takes years and years to degrade so as long as there are no nicks in it and it's a continuous length I don't see the problem in doing it that way.

I eouls suggest using the 15mm White round trunking that's used for live electrics so it should be fine for coaxial. Once I get my dish installed I'm planning to use the same

there is a coax cable that is self repairing, ( it has a mastic type fluid inside, that protects the braiding ) I expect our sponcer will be able to offer help on this,
also as stated the cable will last years with out any further protection

The last time I ran any cable underground I used the blue pipe that the water board use.
As seen here.

Thank you all for the replies. Much appreciated.

I think I am going to go for some MDPE Water pipe as posted by lammy1961. Seems to be best use for the long term.

Thanks

just got my mdpe pipe today. excellent bit of tubing to protect coax under the ground. Couldn't recommend it anymore, really lightweight and very strong.

Now the troubles of waking up tommorow morning and digging a channel and lifting a few slabs :confused:

Make sure u but it at least 6" underground as frost can penetrate to that.
Then you won't have any problems.

I have Sat cable exposed for over 25 years without problems. If it is good cable, the only thing you have to worry about is putting a spade through it.

Well that is not the correct way to do it, having been a master cabler since 2001 I would recommend against this.
But seeing as its your own property you can basically do it how you like :)

I do not think the water company will be best pleased if you don't inform them of the blue acerthean piping in your garden. that is the reason it is blue for water green for virgin media yellow for gas etc. you could have just tapped up your local virgin installer for there under ground cable far better than any sat cable out there.

Your are having laugh, Sat cable is exposed on every sat installition when it is connected to the LNB, how many are damaged by frost?

there is a vast difference between a length of coax pinned to the side of a building and that of a length of coax on or just under the ground.

Well I have 30 meters on a pergola exposed, without problems, for about 30 years, and I have seen the cable companies puting the cable to houses in less than 12" depth of soil without protection. In normal soil there should be no problems. Perhaps you can explain why lengths longer than say 3 meters will be a problem with the weather, in Britain.

Webro make drop cable specifically for burying, if your going to use water pipe make sure both ends are sealed well and ensure you don't damage the coax outer sheath as it will suck up water (capillary action). That's why cable companies use self sealing drop cable.
