Although televisions no longer use analog signals to send video images, they can still be used with digital converter boxes to pick up local channels. The digital converter box connects to the cable port on the rear of the television and sends signals from local stations.
There are free vouchers available for those interested in purchasing and installing a digital converter box. These boxes are available from several different types of stores and range in price, according to PBS. The voucher covers some to all of the purchase price depending on the chosen model. Once a digital converter box is installed, there are no other costs.
