Shielded F/UTP cables + shielded connectors with ungrounded switch - a mistake?

[sl4fko]

A title says it all. I have such a configuration with shielded CAT6 and CAT5e cables connected to a basic 8 port gigabit TPLINK switch, which however is not grounded.

Do cables act like an antenna in my case? Should I buy a grounded switch? Looking at this one: https://www.amazon.com/Tenda-TEM2010X-Aggregation-Unmanaged-Switching/dp/B0D48BLXQL?tag=snbforums-20
It has a screw for grounding on the back...

I doubt the cable will be a problem. How long are they? Are you putting them in a hostile RF environment, like next to electric motors?
