Coaxial Cable Puns

Where does one purchase this type of equipment? Is Solid Pure Silver the way to go?

For a a series of lab tests we will be conducting at my place of work, we will be transmitting HIFI lossless audio over RF coaxial cable to an external antenna, and the focus of the test is on finding a 50Ω coaxial cable around a 1/2" diameter from the device to the external antenna with the lowest loss possible at that diameter. The coax length will be only 40-50ft. The frequency that will be used will be set between 470-490Mhz, and N-Connectors are required.

Because the tests are specifically on the transfer of lossless audio via coax, a colleague recommended using 1/2"+ coaxial cable with Solid Pure Silver center conductors / shielding and Solid Pure Silver RF N-Connectors (apparently a trade secret in a previous audio-related occupation).

Our supervisor has already mentioned to us to start looking where to order one in case we need to compare it against 1/2" Andrew Heliax with a Solid Copper center conductor we already have in stock.

Thank you

I have a 10m 75ohm coaxial cable can I make an antenna out of it

I apologize in advance for this novice question.

For a new home construction:

1. How does coaxial cable enter the home from outside? Simply through a hole in the wall or siding?

2. How do they run coaxial cable to multiple rooms?

Does a single coaxial cable from outside enter the home and a splitter is used to run coaxial cable to separate locations?

My understanding is a splitter degrades the signal, more so with more splits. If you want coaxial cable in many locations, like 4 or more, wouldn’t that significantly degrade the signal?

Or do they use an amplifier instead of a splitter in situations with that many runs?

I assume only a single coaxial cable from outside comes into the house and you can’t have separate outside coaxial cables for each room jack.

Just wondering how and why it became such a ubiquitously good choice. I'm assuming because the copper cable offers the least resistance and reduces signal loss.

There seems, at least to me, to be no have real improvements to this and am curious to know why. Or if there are indeed newer and better performing interfaces.

My wife's cousin and her daughter just moved I into our house for a longterm stay and our current 100mps internet is being taxed with online school for 3, plus lots of 4k streaming and games. We get by, but I decided to start upgrading our equipment and internet plans. I am thinking of going for the 1200 Mbps plan for $90, a speed and price I would have killed for 20 years ago.

I already ran new RG6 cable in my house(internet only, we don't watch cable tv) to our cable modem when we moved into our house a few years ago. I also disconnected all of the old cables and splitters, so only the one is hooked up. Everything works fine for my current setup, but I am in the process of upgrading all of my internet stuff. New 32x8 3.1 modem, up to 1200 Mbps internet speeds, etc.... I have noticed that the coaxial from the street to my house is RG59, so I was wondering what the chances are that it may bottleneck the 1200Mbps speeds.

Would I see a performance increase with RG6 or RG11? Also, who would change it, me or Comcast?

For a new home construction, how does coaxial cable enter a home?

Does the builder run coaxial cable from inside through a hole in the wall to the outside to let the cable company attach their coaxial cable from the street? How does the cable company prevent tampering with the connection point? A lock box?

Does the cable company draw a hole through the side of the house and run coaxial cable directly into the home?

This video shows the builder running coaxial cable from inside to out.

I’ve seen some people recommend running coaxial cable and cat6 Ethernet cable from inside to outside at the point of demarcation. What is the reason for the Ethernet cable?

I've been wanting to put an ADSB antenna up on my roof for a while, but couldn't figure out a clean way to do it. While I was up there over the weekend it dawned on me that I've got a number of coaxial cables run from the garage to the roof for satellite dishes that are no longer in use. Conveniently, I have a computer that could run the Flightaware stick in the garage right where these cables come out of the wall.

Am I able to reuse one of these already run cables to connect an ADSB antenna? Would there be too much noise or is there something else I'm not considering? Thanks.

I'm messing with https://rf-tools.com/lc-filter/. If I make a first-order Butterworth bandpass, for example, I notice that there's a voltage source and then two 50 ohm resistors. Are these 50 ohm resistors meant to represent the inner and outer conductors of coaxial cable?

you know, like there used to be so that way the input couldn't be changed to accommodate things like VCR's and the like, before the advent of HDMI connections or RCA inputs. because now everybody is wanting "a different remote so I can Change the input for my device so I can watch my HuFlixPrime on the TV." I miss the old set-up where you literally couldn't even unscrew the coaxial cable without a special tool to disable the metal collar... I know technology advances and all that, but the problem is they change the input and then they never change it back, and housekeeping rarely checks the TV so the next guest complains that their TV doesn't work... because all of the in room remotes are generic universals that don't have the input option on them.

just gets annoying, encountering a problem that shouldn't actually be a problem because someone wants to stream their HuFlixPrime shows... at 01:30hrs. (Seriously go to bed) that's what they make laptops and freaking smartphones for.

Hey guys/gals,

I am currently analysing the output of my coaxial cable. I connected my cable to a wave generator which analysed the input and output. I made sure to set the boundary condition of my coaxial cable at the end to be 50 ohms so as to match the impedance.

So far so good.

Yet my output voltage signal seems to have been delayed by 3.5% and the square wave input is slightly curved at the top. Is this due to capacitive effects internal to the cable?

1. How does coaxial cable run throughout a home? Does it come from the “curb”, go to an equipment box on the side of the house, then enter the house through a hole?

Is the one coaxial cable then split into multiple via a splitter to go to each coaxial port (ie multiple rooms)? Doesn’t each split degrade the signal somewhat? So how do homes with many coaxial jacks work?

Is there a cleaner way to run the coaxial cable from outside into the home without a hole in the siding? Such as a pass through connector?

2. I don’t have fiber optic in my area yet but can I preemptively run fiber optic out to the same equipment box for a future installation?

SPDIF Input - 2-pin on DAC

How do I connect a TV via Coaxial to this 2-pin SPDIF on my DAC.

Basically, how do I connect a coaxial cable with these 2 pins?

My internet speed is meant to be 100mbs with Virgin UK. However in my room I can barely connect to the internet. My PS4 on wireless gets 1.5mbps lol and my powerline adapter gets me 65mbps but its pure lies for gaming, my ping jumps around all over the place. I read articles which said I need to not have too many things connected close to it, but it only made a tiny improvement.

However, today I just learnt that you can use a Coax cable. I realised I have one, as it was used for my cable (Virgin TV). I brought my router up and realised that it actually works plugged into my Coax!! I tried it with my PS4 directly connected to the Router and I got 100mbs and my ping went from jumping between 65-90, to being between 40-55 which is much better.

I have some questions though. I can not use the actual router. My mum and bro will suffer as I live in a loft conversion and it won't reach them / the ground floor... and I've only tested this Coax cable with the main router. So my questions are:

1. Can I buy a new router and use it as a modem? The Virgin SuperHub3 allows you to go into modem mode. Is it as simple as that? Can my main router still operate while this one does too or will I need MoCa adapters,
2. Do I need those expensive MoCa adapters like this post suggests? https://www.reddit.com/r/YouShouldKnow/comments/6nta9x/ysk_you_can_run_the_internet_over_the_coaxial/ ? (I read it but I'm quite confused and ofc had my own personal questions to ask)
3. If I do need a MoCa then what type do I need? Is it actually going to set me back upwards of £100-150 or can I buy those cheaper MoCa to Ethernet adapters. I'm kinda confused.

My cable modem kept going offline, so I phoned my ISP.

She asked me to remove the coax cable (which was already on tightly and had not been moved for 8 weeks) and reconnect it, which I did.

Removing and reconnecting the coax cable fixed my internet connectivity problem.

Me: "That's weird. The cable was on really tight. I don't understand how it could have had a bad connection!"

Support rep: "Actually sir, the connection wasn't bad. When you removed the coaxial cable from the wall, you allowed all of the static electricity that had built up inside it to disappear. That is how you were able to fix your internet problem today." (Notice she only mentioned static after we had solved the problem, so she didn't just say it to get me to follow her instructions).

WTAF?

Firstly, isn't the outside of a coaxial cable grounded anyway? How could static accumulate inside something that's grounded.

Secondly, I only removed one end of the coax (from the wall, not the modem) and not even for 5 seconds. I didn't touch the end, to allow static to rapidly discharge. Did the static discharge into the air in that 5 seconds?

Thirdly, static couldn't build up on the INTERNAL wire because that's connected to the modem at one end and my ISP at the other, so static would slowly discharge into the devices at the end.

Fourthly, what would generate static electricity inside a coax cable anyway and why wouldn't it be able to discharge itself?

I'm confused because on the one hand, what she's saying sounds like complete bullshit to me. The rational part of my brain thinks there must have simply been a poor connection, and reseating the coax cable just restored a good connection between the outlet and the modem.

But on the other hand, the coax cable is brand new and has no corrosion and was screwed in tightly.. I don't see how the cable could magically get a poor connection when it's new and screwed in tight.

1. Is there any truth to the "static electricity builds up inside coax cable and needs to be allowed to escape" line the ISP rep told me?
2. If there isn't, was it just a poor connection, perhaps caused by temperature changes causing expansion and contraction of connectors?

I have 3 points in my house with coaxial cables connecting to cable/set top boxes. There is a MoCA adapter plugged into my router which I’m assuming connects these coaxial cables to the router. My question is would it be possible to unplug the cable box and use the coaxial cable as wired connection to a nearby PC? Do I just need another MoCA adapter to plug into coaxial cable and a Ethernet cable plugged into the adapter?

Our internet speed was super slow and the company told me that our connection quality has been degrading over the past few weeks. A friend told me that it's probably because of a damaged wire. After looking I found the damaged portion.

I looked up how to cut off damaged sections and add a new connector, but am having trouble figuring out if the connectors I bought are compatible with my wire. I read that the wire should have markings to indicate if it is rg6 or rg59, but mine doesn't show either. The text on the wire says: "PPC PERFECT FLEX 6 SERIES 18 AWG CATV, CL2, CL3, (ETL)us or CM c(ETL)us 3180662 2015 380ft" And these are the connectors I bought

I'm excited to try fixing it, but I also don't want to mess it up and have to call a technician.

I own a condo in a 21 unit building in California. Our cable stopped working, and the cable tech said somewhere between our third floor unit and the garage the cable is disconnected.

Thanks
