If you just recently lost your ability to watch channel 5 and have not done a rescan on your system then tune your television to 5.1 and adjust your antenna until a signal comes in. Antenna placement is critical in how well it will pick up the WMC Channel 5 digital signal. Make sure to pull the rods out as far as they will go. Then place them in a horizontal position, like a set of airplane wings.
Then you must put them perpendicular to our transmitter site. Meaning they must be at a right angle to it, so if you live due south of our transmitter site you must point the tips of the rods East/West in order to get the most signal.
