Rotating Antennae Wiring Question? Answered

Ok, something I've been thinking about for awhile. 

Say you have an antennae/radar dish/etc that rotates 360°. Naturally, you have wires running up to the antennae connecting it to the rest of your circuit/broadcasting/receiving device. How do you prevent the wires from wrapping around the antennae and causing it to stop or causing the wires to break? I suppose you could reverse the antennae every so often to prevent this, but there must be a better way. Also, I figured you could have some sort of connection that rotated around, but it seemed that a rotating connection could be problematic if debris or something got in the way. It also doesn't seem like a very solid way to connect the two devices together. 

Not actually building something here, just a curiosity.

Thanks!

"slip-rings" do this job, but you might need to take care with electrical shielding.
