While doing my annual pc cleaning last month, for some reason, I took
special notice of my Wi-Fi SMA antenna connectors on the back of the PC.
I
have disconnected the Wi-Fi antennas as they are not used and get in
the
way of the cabling they. In my case, to get connected to the internet, I
have a LAN cable from the back of the PC that goes to the hallway to a
TP Link Wi-Fi extender. I find I get a better signal this way as opposed
to using the Wi-Fi antennas on the rear of the PC.
Needed connectors
Back to the Wi-Fi
connectors on the rear of the PC, as I was cleaning, a thought came to
me
that these open Wi-Fi connectors could be a nice RF magnet. In the past
I have issues with RF getting into the PC and to eliminate as much
as I could is a bonus. I did have a few 50 ohm SMA male connectors and I
thought with that I would be good to go. On closer inspection and a
frustrating experience trying to get the 50 ohm to connect to the PC, I
found the SMA connector on the PC was a male and the 50 ohm connector is
also a male connector. This had to be purchased, and it's called
RP-SMA.Once they came in, the connection went very smoothly. So what are your
thoughts on this, most if not all PCs have Wi-Fi antenna options and if
you're not using it and prefer LAN connections should these antenna
connections be terminated with 50 ohm terminators?
Connected and ready to go.

Personally I work the same as you did. Network cable to a wifi extender. I did it for my daughters computer as well. My computer has no build in wifi, same counts for my daughter. But to get back to to possebility of RFI through these connectors. I don't really know. If you disable the wifi radio (in the settings you can) I doubt if any RF will enter the computer through these connectors. If the 50 Ohm terminators help?? I'm not a wizard but in my opinion it doesn't matter if you leave the connectors open. 73, Bas PE4BAS
