This unit has an extended tuning range and can tune most cable channels without using a Cable
TV Converter box. Some Cable TV companies offer "premium
pay channels" in which the signal is
scrambled. Descrambling these signals for normal viewing requires the use of a descrambler
device
which is generally provided by the Cable TV company.
