Of course. That's how you get the condensation in the leg to drain
into the ground.

cage, and the cage must be totally enclosed in the concrete. If I have the
tower legs sticking out of the concrete, will this present a corrosion
issue
or have an effect on the Ufer ground?
No to both. But you didn't mention what kind of tower it is. An Ufer
ground for Rohn 25G may not be very effective (little surface area). Mostly
they're used with bigger tower bases like self-supporters where there is
much more surface area in contact with the soil.
