Scanning for Over-the-Air Channels
• Broadcasters may choose to multicast, which allows them to provide multiple
standard-definition channels in the same bandwidth used to provide a high-definition
channel.
• These factors are outside of DISH's control.
Additional Installation Considerations
• Follow local and National Electric Code requirements for grounding the antenna.
• RG-6 coaxial cable is preferred for the

connection. If you
are diplexing the

cables, RG-6 coaxial
cable must be used.
• You can not use a diplexer to combine the

If you have questions about over-the-air channels, contact the broadcasters, not DISH.
DISH does not broadcast over-the-air signals and so cannot do anything to change over-
the-air signal quality. However, the receiver's digital channel setup menus provide a signal
strength bar that can help you in aiming the over-the-air TV antenna for the strongest
possible signal.
Additional Resources for Over-the-Air TV Broadcasts
For information on channel numbers, you can visit the National Association of
Broadcasters (NAB) web page at
www.nab.org .
Note
: The receiver displays “Transmit Channel” which is referred to on the NAB web page
as RF Channel. These terms mean the same thing.
Another good source of local channel information is available from the Consumer
Electronics Association (CEA) web page at:
www.antennaweb.org . This website provides
recommendations for antenna types and pointing directions.
