BT 80B RF3

Saw a post mentioning the BT 80B RF3 being installed to reduce interference.

 

Curious in that I have had REIN engineers out and this was never mentioned as an option to me. Anyone have any definitive information on this device and what if any downsides it has?

Re: BT 80B RF3

I saw that link and a few others but none of the ones I found were really detailed with regards to what it does exactly, and why or why not you should have it assuming you already have a NTE5 and filtered faceplate

Re: BT 80B RF3

Personally I don't see how it will help considering that it does not look like an external water tight. And if the REIN is before the junction box then surely it will slow the broadband down from there?

Re: BT 80B RF3

It's an internal fitting so I did not expect it to be watertight but I would agree I personally am having a hard time believing it would do any good and yet others have had it fitted.

Re: BT 80B RF3

Well it seems to have helped me having one fitted, the synch rate is much more stable.

 

And it's fitted alongside your NTE5 socket. (Internal).

 

 

They cost £3 by the way.

I think you need to wait a long longer before you can confirm if it has helped you and ofcourse it could be the neighbour issue that was sorted that has actually helped.


Could also be that that it helps on low level REIN but not high levels, when mine is at the worst it has to be at least 30db of extra noise on the line.

Re: BT 80B RF3

To be honest raymie I think most of your line will have to be replaced to fix the issue, because there is only so much an engineer can do before needing to replace.

"I think you need to wait a long longer before you can confirm if it has helped you"

 

Yes of course, but it looks promising, and the RF box definately made the connection more stable, and the problem being sorted next door (Which is about 60 yards away) has made it even more stable.

It may not work for you, but for £3 it's worth tryng, then look for other sources of possible RF interference.

Re: BT 80B RF3

The problem with REIN is that it can come and go, on my line I could show a 100% stable connection from the night of the 19th up until last night and then all of a sudden quite a few disconnections in one go, and stable again every since.

 

Edd, my issues are pretty certain to not be line related now apart from one 200m section which indeed needs to be replaced since it drags down the line balance, the source of the disturbence needs to be found to get any real progress.
