How to Properly Winterize Suburban Water Heater

Ok, I've drained my water heater totally and put in a new anode rod. To properly protect the tank, should I put a mixture of antifreeze back into the tank or is it okay to just leave it empty over the cold season?

Best regards,

    X2... Any small amount of water that may still be in the tank will not cause any problems.
