Grounding Reduces Chance of Lightning?

[Gerowen]

I saw a science professor talking about how lightning rods actually reduce the chance of a lightning strike because they allow electrons on the ground to bleed off into the air over time, instead of forcing them to build up and build up until there's enough of a difference between the air and the ground to cause a lightning strike.

Here's my question. Since my antenna is grounded to a 6 foot steel roofing bolt (think rebar for a coal mine), does it serve a similar function and therefore reduce my chances of being struck by lightning? Is a CB antenna, if properly grounded, actually a tool by which you can "reduce" your chances of a lightning strike?
