Check it out...
Is this real? Does this happen all the time? I'm guessing those are lightning rods on top of the building? Will the Yankees make it to the World Series again? Who shot J.R.?

supposedly (according to the cheesy tourist tour), the Sears Tower gets hit by lightning like 1000 times per year. a grounding system was built into the outer skin of the building.
other useless sears tower facts

oh, and those are officially "antennas" on the top of the building, but who knows about lighting rods...

Im almost positive those are lightning rods, they always have those on skyscrapers to avoid the lightning from actually hitting the building, so instead of dealing with all the catostrophic happenings, they pop a lightning rod ontop of the tower.

There's a good chance that those things are both transmitting/receiving antennas and lightning rods.

Hmmm... so when lightning strikes, does the antenna get a signal boost? If I tune in from Texas, and wait real patiently, think I could hear some Sears Tower Muzac for a split second?

Most tall buildings (towers) are designed with lightning protection systems. They have lightning rods that are mounted on the roof and route any lightning strike to the ground. Generally the grounding conductors are run down openings within the exterior walls.
A lot of single story high-tech buildings (communications and computer centers) also use them for protection.
Even if you install a metallic TV antenna on your house it should be equipped with a grounding rod and electrode.
Just 2 cents worth (I'am bored :) );
