Basically, it keeps the pole from vibrating like a guitar string. The chains are there in case the supporting rod breaks; they keep the heavy weight from going through your windshield.

Well I’ll be! That seems right!

See this to see it happening and the dangers.
This answers a long-standing question for me.

I guessed right ^_^
If vibrating like a guitar string is so bad then tell me why we don’t install those things on guitar strings!?
Guitars have 6 strings. If you attached six of those dampers to a guitar, it would weigh about 240lbs.
Because one is installed on a guitar and the other one is not
