It has made parking a problem as they have blocked some drives and outside my house they hit the water main so that we had a nice muddy swimming pool to have a dip in. This seems to have affected the telephone line as there is so much noise on the line you can hardly have a chat. My broadband keep switching off, so my supplier has activated my 4G mini hub. It works fairly well.
The potential health problems have been around for years and as an Amateur radio enthusiast I have been very close to powerful radio emissions on VHF and UHF which are supposed to fry your brains. It could explain a lot 😣
I'm quite happy with my wired internet so I'm not looking for a replacement yet.
Well, I read enough to make me hesitant to want to upgrade to 5G. Heck, I don't even own a 4G phone yet. I don't have a smartphone. I do own a wifi-only Android tablet.
I may go for one of these new 5G home internet services when they are offered.

Sorry to hear about your problems. Yeah, we had new gas lines put in 2-3 years ago. That was a pain. All of the digging and breaking strips of road, etc.
