Any diy uses for coaxial cable? I've got reels of the stuff leftover after the ISP rewired my building with fiber. Was thinking maybe I could repurpose it for communal hallway lighting or an intercom system for the tenants.

I would like to see that, LMAO
First, power doesn't travel down the coaxial cable... Radio waves do.
>Would power work?
I don't know. I would not trust mains power going down a coaxial cable. I'm sure low-wattage power would work just fine.
cables aren't rated for power
Common misconception. The outside cable plant which is just beefier RG6 runs on 60/90vac over the cable. The low frequency of AC power at 60Hz tends to travel more towards the center of the center conductor which is copper clad steel. Its not the most efficient way to transmit power, but it works. Inserting power onto coax required a power inserter though, which is fairly specialized. Additionally, you'll be hard pressed to find adapters to connect electronics such as LED lights.
House amplifiers are powered with 12VDC without issue. It can be done, but probably not worth the hassle to rig something up.
The old timers in my parts often use old coax to string up green beans, so there's that
what i meant to say was that cables for transmitting power have current ratings, not power since they're not designed to consume power
You're going to see a ton of used cheap security devices that ran on coax, as well as their archivers, for sale very soon. I'm upgrading a Fortune 100 and we're replacing everything analog with digital. Some great deals soon. It's also great as a network extension as it can run longer than CAT6, but you're data limited. Streaming 1080p to a distant WiFi antenna in another building for example. It's more robust than CAT6, and can handle higher voltages, so find use cases where you want to expand a network where CAT6 won't be a viable solution due to distance or power.
>First, power doesn't travel down the coaxial cable... Radio waves do.
They both do. You can run AC or DC through coax.
>Give it back
It's his building anon, he owns the leftover stuff if he didn't pay to have it removed.
this anon knows whats up. You can use these if you need to run data to a far location especially if it's outdoors

> running power through coax
Generally no. Satellite antennas to it (dc bias voltage) but generally the center conductor is steel not copper, so it’s very limited on the amount of power you can get through.
Yes, the steel wire is plated with a few atoms of copper, but that’s all that’s needed due to the skin effect.
>Satellite antennas to it (dc bias voltage)
LNBs etc need 18-24VDC. You can push 5VDC pretty far over that, and that's all the power you need for CAT6/USB. Get creative, plenty of third world countries with this shit just laying around not even being used that you can tap and use in urban environments, much less in a building with a new IP CCTV setup, or just have it laying around. Plenty of ways to use it if you think outside the box and get creative.
>First, power doesn't travel down the coaxial cable... Radio waves do.
Ask me how I know you're moronic.
You lit yourself up because you didn't know.
Seems like about 21v at 550 ma
In a pinch they can be used to have a nice day
use it as a long ass antenna
>I've got reels of the stuff leftover after the ISP rewired my building with fiber.
Give it back
>intercom system for the tenants
how
You could send me a bunch, I need a few hundred feet to rip off some cable

Tbh this.
It's not useful for much if he's not using it for signals anymore, and it's worth almost nothing at a scrapyard.
All the cell phone repeaters have standardized on RG6 coax, like what you have, for the indoor and outdoor antenna runs. I've used it for that. e.g. SolidRF
wifi cable
put one side in the microwave and the other side up your ass...youll thank me later
Like how much? You can make a transmission line PFN if you have a good length.
Also coaxial cable in general is good for conducting high voltage without a lot of radio interference or unwanted discharge, but then again RG-6 isn't the best for that either.
> re-wired for fiber
Fiber is a fricking scam. That stuff is good for 3GB/s nowadays with modern drivers.
> Remind me why they “invented” HDMI again?
Oh, so everything would be DRM, buy new cables every few years with 1.0, 1.1, 1.1.0001a rev 3, and “tuners” were “too expensive” so now everybody gets charged $100 for a $10 rasberry pi clone and calls it “smart tv” to monitor your activities and possibly listen in/watch you watch tv.
i once used the top metal part as a bowl for a diy bong
Good for secure ECM-resistant control of remote weapon systems
