1.5 Connecting cables and devices
There are various types of cable TV (CATV) and antenna connections. Consult
your dealer for the type of adapter, splitter, A/B switch, or combiner that may be
required when connecting the ASUS TV Tuner Card/Box to devices.
The ASUS TV Tuner Card/Box can receive up to 100 channels. If you do not have
a CATV system, you may use an indoor or outdoor antenna that carries only VHF
channels, UHF channels, or both VHF and UHF channels to connect to the ASUS
TV Tuner Card/Box.
