RB grounding or in line chokes

In one of the router board manuals that are no longer on the site, I read a section that talked about proper grounding of the boards. Using metal stand offs and grounding the enclosure etc. It also recommended placing a choke on the Ethernet cable feed through as a good alternative if grounding via a cable was not practical.

As many residential installs are price sensitive and it is often not practical to run a proper ground to a simple satellite mount. I was going to order up some snap on chokes, how ever when going back to the RB site I was unable to find the information.

Is this still a valid option ? and if so what are the preferred spec (resistance, frequency) of the chokes we should use. For only a dollar or so per unit it would be cheap insurance if it prevent even one premature board death or other power related problems.

I think there is some mistake. RB must be grounded always when it use like outdoor equipment and it’s useful to use with indoor cases. Choke on eth. cable only filtering RF noise produced by PHY. It’s important when RB use close with VHF/UHF 2-way radio antenna systems.
