Scanning for Over-the-Air Channels
Peaking Your Over-the-Air Antenna
1 Press MENU, select System Setup, and then Local Channels.
2 Highlight a channel in the local channels list to display its signal strength. Make sure you
see a green signal strength bar and a Locked indication on the signal meter.
3 Adjust the orientation of your antenna to maximize the signal strength. If you cannot get a
Locked indication, you may need to upgrade your antenna or relocate it.
About Over-the-Air TV Broadcasts
Over-the-air TV signals are broadcast by local TV stations from a transmitter tower. You
receive over-the-air TV signals using an indoor or outdoor antenna instead of the satellite
dish. You are likely familiar with analog over-the-air TV signals - these are the signals that
have been used to broadcast TV for many years. New digital over-the-air TV signals are
broadcast and received in the same way. Digital over-the-air TV broadcasting uses
advanced technology like that of the DISH Network to deliver superb picture quality and
CD quality sound. However, digital over-the-air signal reception (like analog over-the-air
signal reception) depends on several things.
• The distance between the broadcast station and your home (the farther away the
station, the weaker the signal)
• The broadcast station's power (the lower the power, the weaker the signal)
• Obstacles between the station and your home, such as mountains, buildings, trees, or
other objects (these may block or reflect the signal before it reaches you)
• Multiple broadcast stations (to receive good signals from several stations, you may
need to compromise in how you aim the antenna or you may need more than one
antenna)
The effects of poor digital reception are different from the effects of poor analog reception:
• Poor analog reception usually causes the TV picture to be “snowy” or to include
“ghosts,” that is, multiple images caused by receiving reflected signals along with the
direct signal from a station. Poor digital reception may cause the TV picture to be
“pixelized,” that is, broken up into small squares of various colors, or to be lost
completely (the TV screen is all black or all blue).
• Digital broadcasts often provide either a very good picture or no picture at all.
