Holds two WiFi/Bluetooth antennas on extension cables above my monitor arm.
My problem was that my Bluetooth reception on my desktop PC was awful with the way the antennas were inherently placed on the PCIe Bluetooth card that I bought myself. The antennas are partially obscured by the all-metal PC case, which I suspect made for the unusable quality of my Bluetooth connections.
I bought myself two RP-SMA extension cables to extend the antennas to a more suitable location: above my monitors, mounted with this print onto my monitor arm.
