Hello:
Have started running cvoax from a receve-only antenna to the house. The coax has a Polyethylene (PE) Outer jacket. With this PE jacket, it's upposed to be buriable. It's becoming a real job for me at my age to dig a slit trench, even a shallow one. But, I can easily just lay the coax on the surface, without any reql danger of anyone stepping on it, etc. It's in a pretty out of the way area. I realize that burying it is undoubtedly best, but in a practical sense, how well does a PE outer jacket stand up if just laying on the ground ? Would be subjected, of course, to rain, and also buried in snow during the winter. Again, it's receive only. Thanks, Bob |

You'll still need a well earthed grounding block where it enters the building. |

Thanks, Bob Other than being damaged by ground traffic in the yard, the main issue is exposure to sunlight which can age the coax faster than being buried. If you can't find a way to get it buried a few inches down, install the coax in some kind of protective tubing. This could be a hose or several sections of plastic PVC tubing, like the kind used for domestic plumbing. You don't have to glue the sections together. I like to install the coax in PVC tubing before I bury it. The tubing protects the coax from being damaged by objects in the ground which can cut the outer jacket, allowing water to get inside. This is particularly a problem in climates where the ground freezes in the winter. It's called frost heaving. I've had rocks come to the surface in the lawn from frost heaving. There's a lot of pressure involved with this process and coax can be damaged if it's in contact with a sharp rock or other object in frozen ground. |

Get a step-on lawn edger, which is a blade attached to a handle, and you step
on it to make a slit in the dirt. Step, wobble it a little to open it up, and make a nice slit, and work the coax down into it, alternating slit and pushing down. Just stomp around to close the slit again. Easiest after a rain. I bury just plain ordinary coax and it works fine, by the way. (You can find the coax again with a portable AM radio. Put radio on the ground tuned to a weakish station, and aim the radio to null out the station. Drag the radio across the area the coax is in in that orientation, and the station will pop up as you cross the coax.) -- Ron Hardin On the internet, nobody knows you're a jerk. |

I use the Hound Dog "Steppin' Edger" from the gardening section of Lowe's Home Improvement. Basically, it's a 12-inch butcher knife with a foot plate on it. Great for laying radials or whatever in the back yard. bob k5qwg Step, wobble it a little to open it up, and make a nice slit, and work the coax down into it, alternating slit and pushing down.

I paid a guy $300 to find wires for the sprinkers in the front yard and then buried a plastic 24oz cup upside down right next to them, Funny now the dirt is covered them but I have some idea what area they are in. Metal dectecting one time I found a year old quarter about 2' down in the dirt in a park that was built 20+ years ago, gotta wonder how that got there. I think the cable will become one with the earth................ |
