How do you terminate SWA Cat 6 Armoured cable

As Harry has said, it's only a belt and braces approach.
If there is an outer screen and it is not connected to earth then it has the possibility to absorb emi and transfer that to the inner wires.

So imo if there is an outer screen it must be grounded, it's not worth not doing so.

Not my area of expertise (not that I have one anyway), however, I did see conflicting advice on reddit with some people saying that earthing at one end only could potentially make the SWA act as an antenna. That said, others said that earthing at both ends could cause problems if one earth is more effective than the other end. I dunno...

Yes there are potential pitfalls with earthing a shield around cables, as has been mentioned - if both ends are earthed then there is apotentialfor the shield to be used as an earth should there become an earth fault. There are others.

However in this case, even if the outer was used forearthing it's moe than capable.

The best way to do it is to earth both ends (best if there is an inner cpc too) according to a video I recently watched that showed the difference it all made to rejection of emi.

On that point, we will have to disagree! Earthed at both ends, can promote interfering current flows, an earth loop, which I have come across numerous times.

Earth loop current does adversely affect the transmission of data along the cable

It will not improve it. Generally, it's a matter of best practice, and best practice is to never ground both ends of any sort of communication cable, audio cable etc., thus avoiding any chance of problems from current flowing along the screen.

Just do the job properly first time. SWA needs a gland on the two ends or you'll end up with sharp points where youve cut through to the inner linner.. Just get a gland off Amazon.. try this one..

The CW is for external and a BW is interior grade. Get a standard back box with 20mm knockouts and fit the gland into it. IT will not move around and end up crap in a month.. Inside the box you can terminate into a keystone or join block if going internal or into an IP65 Cat 5/6 waterproof joint. From there come out of the another 20 knock out with a drill just big enough for a patch lead and go to anything you want.
Personally I would fit a single back box with a bit of conduit from the main junction box to the final and then crone it into a Cat 6 connector jack.

Give you a solid plug in point to go to a router, AP or switch then ..

I would imagine the job is long since done by now!

Quite possibly but if someone else finds the thread it may be useful to them maybe?
