Some cable 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 company.

The illustrations below show how to connect these types of converter/descrambler de- vices with the TV’s VHF antenna jack.

You may need a two-set signal splitter (sometime called a “two-set coupler”) and an A/B switch box from the cable installer or an electronic supply store. With the A/B switch in the “B” position, you can then tune directly to any non-scrambled channels using your TV’s tuning system or remote control. In the “A” position, you can tune your TV to the output channel of the decoder (generally Channel 3/4) and use the cable company’s equipment to tune scrambled channels. Since cable systems vary, you may wish to consult your local cable company.
