At most, it is illegal. I don't understand what garbage laws have been violated. What can I say? The thing is: installing your own receiving antenna only receives electromagnetic signals in the air, not emits electromagnetic waves, so it won't cause any electromagnetic pollution or electromagnetic interference, probably if everyone installs their own antenna. The cable TV company went bankrupt, but the boring advertisements inserted in the middle of TV programs are simply polluting our audio and video. Last year, it was stipulated that from next year, no advertisements or announcements in any form should be inserted in the middle of TV programs. But now, this seems to be a rule that forces people to accept advertisements and seriously deprives viewers of their audio-visual freedom.
