Whats your thoughts?

  

Possible RF magnet
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.
