It seems to me as well as being ugly, noisy, and dangerous to low flying
aircraft, as well as effectively screening low flying aircraft from radar,
these things are likely to also totally disrupt any RF frequencies in the
VHF bands and up, that rely on line of sight transmission to teh horizon.

They are not dangerous to low flying aircraft, because if flying visually
you can see them and avoid them, and if flying on instruments you're a
thousand feet above them or on a properly surveyed instrument approach, and
"properly surveyed" includes taking account of obstacles, obviously. (Of
course if you're flying an unapproved GPS based DIY "instrument approach"
into a farm strip using an out of date GPS database which doesn't have last
week's wind farm in it then that's tantamount to suicide and not really
something for the rest of us to worry about.)

They do sometimes upset radars, and it's not unknown for a wind farm
developer to have to pay to upgrade radars.

You'd have to be doing some really bizarre low flying for them to get in the
way of line of sight VHF radio. Not something I've ever heard of being a
problem.
