Default Grounding Antenna Question

Can I ground out my outdoor FM antenna from the pole?



** AFAIK - the main reason TV antennas are required to be grounded is NOT
because of possible acts by a mighty and vengeful god.

The simple reason is that the antenna may become live AC supply voltage and
so make the TV set (and anything attached to it) inside the premises into a
lethal shock hazard.

This could be because an overhead power cable has detached in a strong wind
or because of an automobile accident etc.

ALTERNATIVELY - the antenna may become live due to a faulty equipment or
wiring inside the premises and so present a lethal hazard to any poor damn
fool who is game enough to get up on the roof for any reason.

Grounding the damn antenna any which way you can is essential.

Other reasons are to earth static charges from the wind and control
surges induced by near strikes.
