To Brian,
In all fairness, I would not like my Freeview or Freesat to be affected in the same way as on LW, MW or SW.
As a born profoundly deaf person, I rely on the subtitles and pictures working just like you rely on radio working as it's our link to the outside world.
So I don't use power line networking at my house and just have the minimum of WiFi so that's just tablets or smartphones.
Everything else is all ethernet wired, even the music systems, all smart TVs, all printers and scanners, all network storage etc.
The loft looks like a data centre server room as a result, with over 64 co-ax cables and over 64 ethernet cables coming in
