You and I understand that EMT is not for U/G installs but some people don't know the code and just think any type of conduit is ok to use. So just saying metallic raceway can be misunderstood by most.Comment

Can you access the rebar? Is so there is no better earth ground than a concrete encased electrode or UFER ground. Every ammunition bunker in the USA uses a UFER ground. FWIW a UFER ground and NEC Concrete Encased Electrode are not quite the same thing, same principle.Comment

Steve how are you running the Coax. Underground or over head?
If underground use a metallic raceway, and use the raceway as your bonding cable. It is permitted to be done that way as it is a pipe, plate, or rod electrode. It will be better than a #6 bare Copper wire. If overhead use the messenger aluminum or steel cable
These are on the AM broadcast band, the ground rod at the tower is one of those chemical grounds, the ones that you set in a hole with bentonite and fill with something that gets good electrolytical action going, I think.Comment

A few days ago I went to home depot and bought one of those water jet nozzles for the garden hose, the kind that's sort of a poor-man's pressure washer. I put it on the end of a 1/2" PVC pipe with the appropriate fittings. It bored a 1" hole under my 36" sidewalk in about two minutes, I couldn't believe how well it worked. I could have gone under my whole driveway if I had enough pipe.Comment

It's run in the PVC now, should we take it out and run it in dirt instead? Or do you mean just for new installs?Comment

If bare get it out and run in dirt. You want bare to shunt off lightning current to earth as much as possible. Not to mention it could get warm enough to damage coax. Doubt it but possible.MSEE, PEComment
