Cable and satellite companies scramble digital signals from and require a tuner to view them.

An exception occurs if yourdigital TV is a digital monitor.

Then the tuner is the CableCard.

Most big box and electronic stores carry a good selection.

Some allow the recording of digital content.

External TV tuners require a strong signal to provide excellent reception.

Digital signals are more sensitive to distance and obstructions than older analog signals are.

If there is no signal at all, an antenna won’t help.
