I am having trouble finding a usb hub to increase ports on my laptop that does not generate  significant RF.  I am wondering if the one you sell is low RF

Ultimate Grounding USB to Gigabit Ethernet Adapter with USB 3.0 Hub

This item has not been tested for RF.  It's purpose is to ground the computer and the Ethernet cable plugged into it.  It also is a passive device - so it does not have an AC adapter power supply - which greatly cuts down on anything generated by it.

I would recommend trying the unit with your computer to see how the two devices work together and if it meets your requirements.  You can always return the item within 30 days if you have any issue with it.
