Severe thunderstorms- do we need to lower the TV antenna?

Weather Geek here; ultra-slow motion photography shows that often, the ground sends up weak "feelers" to balance the negative and positive charges in the air. These feelers reach farther if they are coming from a pointed source. Meanwhile, the storm clouds are sending feelers of their own. When these two sources meet, then a cloud-to-ground bolt is delivered. Dr Tim Samaras documented this interaction with a 10,000 frame per second camera, because it real time it happens so fast you can't see it occur.

When I'm camping, I try to NOT provide a pathway for feelers. Antenna down because it's pointy, jacks up, slider in.
