Somebody in one of these two groups recently said that a concrete based house means you're earthed. Concrete is a bloody good insulator!

Negative, if one looks at an AM radio station the tower is used as the
antenna. Note a big ceramic insulator between the tower and the foundation.
the is a spark gap on the insulator for lighting. If the transmitter is
active then a non conductive ladder to climb the tower. That is why
maintenance is performed at night because they are off the air.

The base can get wet.
