I will be getting UFB and putting in structured cabling into a 1960’s house. I think Snap is a good option, and their FritzBox has an integrated DECT base station for phones, which is cool.

But if I have the FritzBox in the Home Distribution Box along with the ONT, Switch, etc. won't the wifi and DECT signals be blocked (or at least severely attenuated) by the steel cabinet door? Can you get plastic boxes that let the signal pass through, or is there another way?

Thanks
