Is my radio dead though?

Hmmm, color me skeptical regarding those pointy devices that are said to be able to dissipate a charge.
If that were the case, then trees with all the pointy branches and leaves would never be hit.

Josh:
Leaves and branches are a bit less conductive than stainless bristles bonded to a grounded metal tower.

pinto vortando:
Well, are those pointy thingys UL tested, labelled, and listed as well as permitted by NFPA 780 ?
What do insurance companies have to say about them ?
Dunno…  just asking,
have never seen them used on data centers, cell sites, substations, and the like.

Josh:
As to ul testing, insurance, code compliance, fkifino.
