In many cases, TV reception equipment has long wiring between the antenna side and the booster side or TV side, so it is easy to generate a potential difference (easy to be affected by lightning surge).
In particular, TV antennas installed outdoors are susceptible to lightning induction through coaxial cables, and if they are wired to multiple homes in an apartment building through a booster for communal reception, they are even more susceptible to lightning surges.
