and connect it to the DVD/VCR. Then connect the DVD/VCR to the TV. Below are 3 common methods of connect-
ing an antenna system to a DVD/VCR. Find the type of antenna system you are using and follow the connection
diagram.

a special channel which is scrambled, you must have a descrambler box for proper reception.
