Consider running the coax through a garden hose before burying. You won't have to dig it up if you want to change or remove it. You can use a barrel connector on the existing coax to pull the replacement through. - Nice video!
@JxH Жыл бұрын
A PL259 connector is about 18mm in diameter. Common 5/8-inch is 15mm. Even a rarer 3/4-inch hose (19mm) would BARELY accept it, and with even the slightest crush from being buried, forget it. Don't use a garden hose, use a larger and stiffer pipe maybe 1-inch diameter. Or don't bother; just direct bury and rip it out when it's going in the garbage anyway.

@@JxH I think that the idea of the hose or conduit was to make any replacement of the coax easy if that becomes necessary, just use the old coax to pull the new line through, - no need to dig up the lawn to re bury the new run of coax.

When you run a bolt through thin wall pipe like that no matter how much you tighten the nut you'll never really get it tight. It just collapses the pipe. Instead, use nylock nuts. Those are nuts with a nylon insert that will stop the nut from spinning freely. Just snug it up, but don't distort the pipe. The copper coat is a good thing, too.

If you have those DTV pipes, measure the diameter and goto HD or Lowes and get a conduit pipe in a smaller size so it can slide inside the DTV pipe. I dont remember the exact size however, if I were to guess, I would get a size 1/4 smaller. Maybe 1 1/2" diameter. I can put 2 conduits together without using guy wires. Remember to get a smaller size diameter for the upper sections and use the bolts in a crisscross pattern to prevent twisting. I hope that clarifies it a little. Happy New Year!
