DISH Network 612 ユーザーズマニュアル

You may be able to receive a poor analog signal but not be able to receive a digital 
signal at all.

To get the best possible digital signal reception, make sure you use the best over-the-air 
antenna for where you live:

You can receive a limited number of channels using a rabbit ears type antenna on top 
of the TV set, or a much larger number via a large UHF/VHF indoor/outdoor antenna.

The higher the quality of the antenna you use, the greater its range and the better its 
reception will be.

Digital OTA Broadcasts are Still Developing

Broadcasters may still be testing digital signals and their strength, and may stop 
broadcasting without notice, vary power output, or turn it off.

Some broadcasters do not yet have permanent transmitter tower.

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 Network's control.

Additional Installation Considerations

Follow local and National Electric Code requirements for grounding the antenna.

RG-6 coaxial cable is preferred for the O

 connection. If you 

are diplexing the O

 and S

 cables, RG-6 coaxial 

cable must be used.

You can not use a diplexer to combine the O

 and S

 cables if using an amplified antenna.

If you have questions about over-the-air channels, contact the broadcasters, not DISH 
Network. DISH Network 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.

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.
