How to run ethernet outside and up exterior wall?

[ARCHIVED THREAD] - How to run ethernet outside and up exterior wall?

Posted: 4/21/2021 2:31:21 PM EDT

I'd like to run a few ethernet cables from the basement through the exterior wall and strait up to the attic. It's really easy to get to both spots, I'm just not sure what type of conduit and fittings to use. I was thinking maybe using two of these:

and some of these:

Any ideas?

Thanks

Why does it need to be so well sealed? The cable isn't affected much by weather and it's low voltage so there are no code requirements. You can just calk the holes where it enters/leaves the house.

ETA: I would just use gray conduit to keep the cables neat and protected from getting snagged etc. You could just calk the ends to keep bugs out or stuff with steel wool or similar. No right angle fittings required.

Mostly wanted the conduit so it'd look nice and in case I want to add/remove cables.

the grey PVC type conduit will work fine, I would use at least 3/4" and I would use the right angle conduit bodies with the removable covers on each end to ease in feeding and keep critters and weather out. Keep in mind it will flex and sag if it gets hot in the sun so secure it well if you have any long horizontal runs, learn from my mistakes.

Ethernet jacketing isn't UV-shielded, so UV will break it down over time. The conduit that OP listed IS UV-shielded.

Plus, sometimes you gotta replace an ethernet cable. It's a lot easier to just pull new through the conduit.

That's what I used and the grey is a close match to my siding.

You can buy UV shielded... I get UV shielded from a friend that owns a local ISP. They use it for runs up their P2P towers.

We've used liquidtight non metallic tubing and fittings. It has worked well. You probably don't even need fittings to exit/enter the house with it.

Conduit is overkill and unnecessary for that.

Run some UV-stable/outdoor rated cable with cable staples to hold it to the wall.
I honestly wouldn't even mess with FTP and the associated grounding headaches it introduces.

Good outdoor-rated cable will survive on a tower for years.

I'm with everyone that has said to use UV-rated outdoor ethernet cable. There is no need for conduit. One thing to remember when running the cable, make sure to add a U shaped "drip loop" where it enters the structure. The helps keep any water from running down the cable and into the hole. And yes you still need to calk the openings where the cable enters.

PVC conduit for this project is going to be what… $20?

Go ahead use conduit. Especially if you are going to have multiple wires in there. Over kill it with outdoor cable in the conduit too. Outdoor Ethernet cable is filled with a gel to prevent condensation from forming inside the cable.

Conduit is the answer. Future you will thank present you.

Besides, having a bunch of bare wires running on the outside of the house is gross.

Plastic ENT conduit with 4x4x2 boxes or angles that have access ports so you can fish and pull wire. Use at least 1” diameter tube. They have flexible tubing if needed with compression fittings.

Another vote for conduit. I have some wiring coming from the house for the A/C and another that was for an external ringer hooked to my land line, and my brother damaged both of them with his weed trimmer.
