Hole in Brick where Coax Passes through......Best Way to Seal Around the Coax?

[merlin]

mostly concerned about keeping bugs out

Pack some steel wool in there, no bugs.

National Electric Code requires that the new ground rod be bonded to the existing electric meter ground rod. Not doing so can result in difference of potential.

Should I add a Lightning ARRESTOR coaxial ground block?

Where I bore a hole in walls, brick, cinder block, I run some PVC pipe to accomodate coax. I have been using FlexSeal, especially the outside.
Does a nice job.

I've actually used tubing wire conduit even though it runs under a deck then through the crawlspace.

Plumber's Putty is cheap and lasts a long time.

Should I add a Lightning ARRESTOR coaxial ground block?

It is required by NEC where the coax enters the home.

If you really want it professional order a single boot Microflect plate with the appropriate sized coax gland. Screw it to the brick with sealant over the hole.

Should I add a Lightning ARRESTOR coaxial ground block?

It is required by NEC where the coax enters the home.

Rephrasing the question: Should I add a Lightning ARRESTOR in series with the coax's center conductor?

No, it is not required by the NEC. However in mission critical installations it is suggested the center conductor have a lightning arrestor in series to shunt the surge to ground, but not required.

The NEC only says the outer shall be bonded to ground.

820.93 Grounding of the Outer Conductive Shield of Coaxial Cables
Coaxial cables entering buildings or attached to buildings shall comply with 820.93(A) or (B). Where the outer conductive shield of a coaxial cable is grounded, no other protective devices shall be required.

Just don’t do this

I would pass it through1/2" PVC. I do this when passing electrical through brick or cinderblock(NEC Requirements). Then use some duct plug. I can't remember the bit size.....will have to look when I get home, but it's just big enough for a good interference fit through the brick. Then patch it over with the duct plug.
