I also tested if the interferance gets stronger if my GPU is at full load. You can see that there is more noise from 1,3ghz to 1,5ghz, but the signal mentioned before doesen’t get stronger.
I also shielded the antenna with a thin carbon sheet that reduced the signal loss. I will test some more shieling soon.
The ferrites also arrived yesterday, but the don’t seem to effect the signal when clamped around the USB cables and Antenna cable.
That is what you get for putting a plastic window in the case…
Replacing the lid with the optional closed version (usually available) could help a lot.
But of course such a case is clearly not designed by an RF shielding expert so it probably has many
other leaks as well (like covers without metal contact every few cm). You know, the "contact fingers"
or even spungy metal you find in a professional case.
Also the metal looks like it’s anodised, so there is no perfect RF shielding. But thats not the purpose of a pc case, it has too look good and must be stable.
I think shielding the case of Outernet, that i planned to print, will be enough.
even the not grounded Carbon helps to reduze the noise quite well.
Apparently different people have a different opinion on what the function of a PC case is…
In itself that is not bad, but you clearly are affected by the problems resulting from using a beauty case
instead of a functional case. So then you should start thinking about it…
Of course not! The interference that has leaked out of your PC will enter the Outernet receiver at
the antenna, and you cannot shield that. The only thing that could help is to increase the distance
between the PC and the Outernet system.
The back of the Antenna is pointing into the room where the PC sits, so i can shield it from the back. The antenna is pointed away from the PC.
I already shielded the back of the antenna with a carbon sheet that leans against the Antenna. An it works! I get much less interference from my PC, then before.
I already wrote above, your case is probably crap. It has lots of other leaks than the window.
A long slot, e.g. where a side panel meets the case frame without proper electrical contact every
few cm by use of contact fingers or similar will leak as much as a window does.
Unfortunately a case like that can often be sold, especially as separate part for later integration by
the customer, no matter if it meets basic requirements for RFI.
Now that you are a victim yourself you notice this, but normally PC owners are not aware that their
equipment is causing real interference in real life, and will wave comments away. And their neighbors
often lack the technical knowledge to know that some interference they have may be due to the PC
nextdoor.
wait wait wait…it’s not “Crap” only because it doesn’t shield the RFI
My case is realy sturdy and has a lot of room for hdds and ssd etc. It looks nice to me and has good cooling (A lot of Fan mounts) and Dust filters. That are some of the aspects that matter for a PC case. RFI shielding is not one of them!
Also it can not cause interferance for any of my neighbors. Even in the next room the interference is not there anymore
So there is no problem with the lacking RFI shielding, if you don’t use outernet or similar in the same Room.
Please stop raging on PC cases…also what case are you using or would use that is RFI shielded?
