with 20+ years in wireless telecom, I would have the same concerns as fat_lazy_union if I spotted the tx antenna facing towards my future residence, and I would take the same action as fat_lazy_union did.

Some antennas, such as those used for radio and television broadcast transmissions, use power levels that are much higher than those used for cellular and PCS antennas – base stations. Even though all broadcast stations are required to demonstrate compliance with FCC safety guidelines, in some cases there could be a potential for higher levels of RF exposure.
