It has been our experience that one piece units work better to replace your cable company's converter than a 2-piece unit. Although 2-piece units tend to be less expensive, they tend to work less efficiently as well. A descrambler is a device that restores the picture and sound of a scrambled channel. This unit contains a converter and a descrambler, enclosed in a common box. This is also the most common type of equipment supplied by the cable company to subscribing customers.
Customers usually pay a specified monthly rental fee for such equipment.
