Connecting an Over-the-Air Antenna
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 the transmission of digital signals and their strength,
and may stop broadcasting without notice, vary power output, or turn it off.
Some broadcasters do not yet have a 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
VER-THE-AIR ANTENNA IN line. If you are
diplexing the O
VER-THE-AIR ANTENNA IN and SATELLITE IN cables, then RG-6 coaxial
cable must be used.
You cannot use a diplexer to combine the O
VER-THE-AIR ANTENNA IN and SATELLITE IN
cables if you are using an amplified TV antenna.
If you are using a diplexer to combine the TV2 Home Distribution signal of the receiver
and the O
VER-THE-AIR ANTENNA IN, you must use a Super Home Node to prevent
accidentally broadcasting the Home Distribution signal via the 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, when the optional over-the-air
tuner module is installed, the receiver's digital channel setup menus provide a signal
strength bar that can help you in aiming your over-the-air TV antenna for the strongest
possible signal.
