What is that tool called?
What is that tool called? I am trying to look them up to see if they are available locally.
I lucked out. Just had an electric dog fence put in and the installer dug me a trench with his machine. Put in LMR 400
One of the drawbacks of direct bury is gophers. We have a surplus. That is why I put in 2" conduit with electric boxes on each end.
Just took the station down preparatory to a move to a new QTH. Had 3 runs of 9913 coax, a #4 copper wire as part of the single point ground system, an 8 wire rotator control cable and an 8 wire remote switch cable all buried 4 feet under ground inside conduit for nearly 15 years. Also through the conduit was a 3/8 inch paracord pull line. All pulled back through the conduit and appear to be in perfect shape--good enough to use them at the new QTH
They're certainly proud of their product
Only 19 left - better order soon
If I need to bury coax (and I do) I use the water blast from a garden hose or a pressure washer to cut a path into the soil. Easier on your back and works much faster than "digging."
Later followup by filling in the path with a bag of:
It's NOT the same...
Jacket: Non-contaminating PVC
Shield: 95% braided copper
Dielectric: Solid polyethylene
Center conductor: 7-strand copper
Jacket: Type III polyethylene
Shield: 95% braided copper over aluminum foil
Dielectric: gas-injected (foamed) polyethylene
Center conductor: 19-strand copper
However, they're both 0.405" OD. On the BuryFlex cable, the PE jacket offers better resistance to moisture ingress. The aluminum foil shield offers 100% shielding. The foamed dielectric offers lower loss. The 19-strand center conductor takes repeated flexing better.
DX Engineering sells DXE400MAX, that appears to be identical to BuryFlex. Orders over $99 include ground shipping (at $0.95/ft, order ≥ 105 ft).
Sealant-lined heat shrink tubing. 3/4" w/ 3:1 shrink ratio works well on UHF males fed w/ 0.405" OD coax. The last time I bought it, I purchased a 4' length of thick-wall shrink tubing from McMaster-Carr (#7861K56, $19.10).
