Drilling Hole in Wall to Thread a TV Antenna Coaxial Cable

Hi, I'm not a contractor or construction worker - just a homeowner. I want to thread a TV antenna coaxial cable from the antenna through the living room wall to inside the house to connect to a digital TV. I'm not sure how complicated this is? Hazards and dangers to be aware of? How and with what do I seal the hole around the coaxial cable? Tools, equipment, materials, supplies needed? Thank you!

Re: Drilling Hole in Wall to Thread a TV Antenna Coaxial Cable

Generally you just need a drill bit slightly larger than the diameter of the coax and log enough, or a bit extender, to go trough both the inner and outer wall. Make sure there is no electrical where you are drilling. If the walls are insulated drill through one wall and spread the insulation apart with a stick or crew driver. Feed the cable through to the proper length needed plus a little slack. Seal the outside with caulk around the coax. Stuff some insulation in around the coax and seal the inside with caulk. Or you can buy a couple of coax bushings, one for outside and one for inside.

Hi Jack,

Thank you so much for sharing your helpful thoughts/suggestions.

What would you say is the best way to "Make sure there is no electrical where you are drilling"?

Is there a tool like a stud finder to check for electrical in a wall?

Have you ever happened upon any videos showing a person how to use a stud-finder and the tool used for checking for eclectical in a wall?

Thank you again for all your kind help.

Here is a Youtube video https://www.youtube.com/watch?v=MjYYRT8m0QU

And a detector that is sold by Walmart https://www.walmart.com/ip/Stalwart-3-In-1-Metal-Live-Wire-and-Stud-Detector/55485903#about-item

That will help make sure you are between studs and there is no electric or piping.

Re: Drilling Hole in Wall to Thread a TV Antenna Coaxial Cable

Hi JL,

Thank you so much for sharing those links.

Is it ever OK to drill through a stud to thread a coaxial cable?

I tied to attach a .png file of the photo of the area on the outside I was planning to drill the hole but this site stated it was not an appropriate format. Does this site only accept .jpgs?

It would be drilled about 4 inches above the baseboard and to the right (under) of those two electrical outlets.

Do you anticipate any problems with that course of action?

Thank you again.

You can post png, jpeg and other files to a free service like Photibucket then post the link on here.

Try to keep distance from electrical because it can induce noise on the coax.

I would not go through a std because you will weaken it.

Hi Jack, - here is the photo of the area (with arrow) where I was considering drilling the hole - http://i.imgur.com/eOJpYeZ.png
It's my understanding a Stud Finder doesn't find neutral wires. Which tool and/or technique would you suggest I use in checking for any neutral wires in/near the wall before drilling? Thank you again for all your continuing help and insights. Happy Easter to you and your family. Best.

Hi Jack and all you good folks,

It's taken me days to be able to log back in so my apologies.

I’m so very appreciative of all your help and insights. It’s my understanding that a stud finder can’t detect neutral wires so I’m wondering which tool or technique I can apply to search for neutral wires before I start drilling into the wall?

Also, does it matter whether you use a reversible, variable speed 18 volt drill –vs- impact driver as long as I’m using an 8 inch 3/8 bit to drill through the wall?

How does that coaxial bushing - (is that what that black device in the photo above is called? It wont copy and paste here.) - come into play?

Do I slip that over the coaxial cable going into the wall from the outside and another one coming out of the interior side of the wall?

Here's where I'm considering drilling the hole for the cable - about 3-4 inches above the deck floor and 3-4 inches below the 2 outlets and to the right of them.

Hi Jack,

Many problems trying to log back in since our last exchange.

Here's a photo of where I'm considering drilling a hole from the outside threading the RG-6 coaxial cable through.

Also, do you think this Multi-User Detector - https://www.youtube.com/watch?v=08733z958qY

would be sufficient in testing for neutral wires (not just hot wires)?

It's supposed to test for studs and hot wires but I wanted to be sure there is noting in the wall where I'd drill.

Thanks so much for all your appreciated hep.

Just drill and you should be fine. Pipes normally don't exist on external walls, unless your in the kitchen area and even thats rare in modern homes to have plumbing on the external wall.

Find your location to drill, its better to drill from the outside in, certainly if you are drilling through brick try to hit the mortar line rather than the brick. A good way to check for any obstructions in the wall is go inside, drill a small 1/4 inch hole through the sheet rock , knock on the wall to hear a hollow noise to determine in between studs. Drill just through the sheet rock then stick a long drill bit or rod with your hand and move it around to feel for anything.

The picture you posted is a power plug outlet cover, the wrong thing to use. Or call your cable company have them do it.

Re: Drilling Hole in Wall to Thread a TV Antenna Coaxial Cable

Hi Jack,

That photo of the coax bushings, one for outside and one for inside.... - how would you suggest I apply them?

I've got the coax cable threaded through and caulked both the inside and outside.

Is there a way to apply them now?

Or are they applied before caulking?

Or are they used instead of caulking?

Are they made of rubber?

Where have you found them?

Hardware stores I've called don't seem to stock them.

Thanks so much
