Wireless mic over tv

Hi everyone, I apologize if I'm posting this in the wrong forum. I'm new here. I have a problem that I can't find an answer to. Maybe I'm just using the wrong search terms, but google has been no help either. I'm being harassed by my neighbor via what I'm pretty sure is a UHF wireless mic. Maybe it's not, but all the technology that I've looked at points to it. I use a Korean cable service (I'm in Seoul), and lately I've been able to hear my downstairs neighbor spewing profanity over the tv speaker. What happens is the volume drops to an almost radio quality, and then he does his thing for about 10 seconds or so. I know he can hear my tv, so he can find the channel I'm on. I'm sorry if I'm in the wrong place to ask this. I just don't know what else to do to resolve this. Any help at all would be helpful.
