the cable would be extremely long. but hypothetically would it work? and if so why don’t ships carry them?

Tech1: You think we should’ve used shielded cable? Tech2: Nah, that outta do it. We’re done here.
I recently got my house wired with CAT6A. The company who did it installed *shielded* cable, against my wishes. Shielded cable is *not* needed and is a huge pain to terminate and deal with. They even put unshielded terminations (first red flag).
Anyway, I told them they had to re-terminate with shielded keystones and use a grounded patch panel if they didn't want to rerun the cable.
Instead, they re-terminated them with shielded heads and plugged them directly into the switch. They are telling me this is grounded. Are they correct? I tend to think that you need to have a separate grounded patch panel, but maybe the switch provides the grounding?
In this image there is a wire called shielded cable. It has a connector with what looks like 5 pins that connects the shunt to the voltage monitor. My question is. Does this shielded cable wire need to be used, or can wire that has already been run be used? The wire ran is 16awg. The reason I ask, is because the voltage monitor is going to be installed about 12-15 ft from the battery itself. I already have wire ran for it, & would like to use that, however, if that shielded cable absolutely needs to be used for whatever reason, then I'd have to 1: buy a length long enough & 2: run it again. (Which may be difficult, with that chunky connector it has). So it's either that, or can someone help me maybe find the connector type & then I could connect that to the wires already run. Thanks, peeps!

I have had mixed success using external HDD drives, but the sort of annoying mixed that isnt consistent or makes sense. I had strange problems, such as wifi cutting out, or my network adapter crashing. Certain drives would work with certain ports on different machines, but not all the time. I had assumed it was a power draw thing, despite the drives being externally powered.
Turns out, cheap USB3 cables can leak interferance right in the 2.4G Wifi band. This explains a variety of issues I've had on multiple machines with poor connectivity using external drives (and usb expanders). In case you have had similar issues, you can try a higher quality usb3 cable, simply plug the drive into a usb2 port (slower speeds though), use 5G, try moving the drive further away from the wifi antenna, or ditch the wifi dongle altogether and get wired with ethernet.

Will the USW-Pro-24-PoE automatically ground shielded cat6 cables? Or do I need to do something specific to ground them? This is assuming the shielded cable has a properly attached shielded metal connector.
Also, is there any way to test if the cable is grounded once it is attached?
Thanks!
Hello!
Please forgive my lack of knowledge, I have tried to find resources online but I figure the best way to get this question answered is by asking someone more knowledgeable than I
So I have xfinity wifi with the 600Mbps speeds coming from my modem in my living room and would like to run ethernet into my bedroom for my PC. My PC has a wifi antenna but it limits my speeds to like 90 Mbps, I figured this out by putting my PC in the living room connected via a short ethernet cord and got 700 Mbps.
So now I have a big long cat5e ethernet cord that I put two connectors on to test connection speed loss and I am back down to 90 Mbps, The cable is easily about 100 ft long, I don't need the whole thing, I just wonder:
Should I run this cat5e cord under the carpet and cut it at the length I need and hope the speeds improve or should I purchase a shielded cat6 cable instead?
Some additional info: Currently the wire is all tangled up in itself, not sure if this is an issue, and I do live in an apartment so there are other people nearby and there is a power line outside my door like 20 ft away
TL;DR: got lots of cat5e cord, speeds dropping from 700 to 90 Mbps, not sure if I should stick it out with this cord and cut it shorter or get a better cord, please halp
EDIT: Thank you all so much for all of the replies with helpful suggestions, I really appreciate it.
EDIT 2: THANK YOU ALL SO MUCH FOR YOUR HELP, I found thee issue, it was a bad termination on one end of the cable. I greatly appreciate all of your help and am very grateful for the knowledge I now possess.
Whether I was running Cat5e, Cat6, or Cat6A I would always just use the standard clear plastic RJ45 connector.
- Because that used to just be the only thing there was to use (there were no metal shielded RJ45 a few years back).
and
- Because at some point I had ordered a tub of 1000 of the dam things and I still have probably 500 left...
However, now that there is Cat6A, Cat7, and Cat8? patch cables available that all come with the metal shielded RJ45's, I want to know if there is any difference when running higher tiered cables in lower tiered connectors. Google has no luck with this one. Has anyone here ever done any testing with this scenario, or does anyone know of any previous documented cases where someone has tested this?

Do they ground shielded cables, or do I need to do something to ground shielded cables. I have a cable that has to go within a couple inches of an electrical wire for 50 feet.
Edit: I contacted ubiquiti support regarding this and they confirmed that shielded cables will be grounded through the switch, which will be grounded through the power plug. The manual used confusing should terminology that could mean multiple things. Here is their exact response.
"It simply means that plugging the device to the power using the power cable provided with the device will ground the device through the wiring. Hence, you don't need to ground the switch seperately."
Brand new fire alarm and electrical apprentice helping install a new system.
I've been told by my Jman to tie together the shields in our speaker circuit, while others have told me that's a waste of time and they don't do that.
Could anyone explain to me the importance of tying the shields and what it does from the technical/theory point of view? Thanks in advance.
Edit: thanks so much for all the help guys! My Jman is the fire alarm guy at our company and teaching me the right way. I've never had any fire alarm experience so it's great to know the technical reasons behind things for those who tell me the wrong things!
So I have a client for whom I'm currently installing low-voltage (Network, CATV, Whole Home Audio, etc.) cabling in his house which is currently under construction. He decided to go with shielded F/UTP CAT6a cable for most of the cabling, and while I have experience in installing systems like this, this is my first time dealing with shielded cable.
Please, don't reply asking why shielded cable, because the answer is the homeowner wanted it, and so that's what he is getting.
So, I read many posts across reddit, google and other sites on the internet, and scoured YouTube for any definitive source about how to properly ground shielded cable. with answers ranging from it doesn't matter (BICSI report/presentation titled "Mythbusting: Shielded Cabling") that claims that all the claims, e.g. Antenna effect, ground loop, baked-potato effect, etc., about grounding are all busted and therefore not legitimate. However, many other articles and forums claim if not done properly that it all of those effects mentioned above can cause havoc in a network.
I'd really appreciate a good solid answer from someone who can explain in a step by step method what is needed to properly ground these shielded cables. Particularly, can I ground the shielded patch panel to the bare copper ground wire that runs throughout the house or do I need to do something more?
I appreciate any information that can shed light on this for me. Thanks in advance!
Hi all,
I'm trying to replace an old Clipsal system with KNX in an old house. The Clipsal cable is unshielded whereas KNX is shielded to prevent interference (to my understanding).
Would this become an issue if we use the cable that is unshielded with KNX? Or would you recommend us to change it to a shielded cable?
Any input/direction is greatly appreciated.
Many thanks :)
I’ve been noticing Z drift on my CNC and I think I’ve determined it to be caused by the VFD spindle and it’s wires. I ordered some 18/4 shielded cable as none of the cables on my machine are shielded. Maybe a dumb question but do I attached ground wire in the cable to the enclosure that my CNC drivers, power supply, etc are in? Just want to make sure everything is grounded properly to avoid any interference.
Will braided cables suffice or do I really need shielded ones for my turntable to phono preamp?
I'm using 2/0 AWG cable in an EV conversion and trying to decide if I should spend the extra cash on shielded cabling.
Is there a standard measurement to determine if shielding is necessary?
Hi all, I'm going to be pulling about 8 new ethernet runs up to my attic and then down to the bedrooms. They're going to be in a PVC conduit I'm putting in up through a chase that runs from my basement mechanical room all the way up to the attic.
What's complicating this is that duct work is also in this chase running up to the attic, as well as some electrical cable runs.
-
Do I need plenum-rated/CMP cable for this or is that just when the cable will be inside the ducts?
-
Should the cable also be shielded (F/UTP) given how close it will be to the romex?
I don't have an issue spending more for this, I just want to make sure I get the right thing. Thanks!
