Your television may not receive ghostly and snowy images since the 2009 transition from analog to digital signals, but digital broadcasts are not perfect. From channels blinking off and on to channels not being received at all by your digital converter box or television, digital TV broadcasts have its own unique set of problems. But there are ways to boost your digital TV signal reception and you don't have to modify your television or digital converter box.
Making Antenna Adjustments
Turn on your television.
Video of the Day
Move any objects blocking your television's antenna to another location. Aim the antenna toward a window or other opening to increase signal reception.
Click "Menu" on your television or digital converter box's remote control. Navigate to the "Signal Strength Meter." Move your television's antenna slowly as you watch the strength meter to position the antenna in the highest strength location possible, if you are still getting a poor signal on certain channels.
Place the antenna on a shelf or location higher or lower than your television. A change in antenna location can improve reception.
Turn the rotor knob slowly on the antenna box that controls your outdoor antenna to improve the digital TV signal reception.
Connecting a Bow-Tie Antenna
Add a bow-tie antenna to your current antenna, if you are still experiencing reception problems, by turning off your television and attaching the bow-tie antenna to one of the aerials on your television's antenna.
Plug the bow-tie antenna's connection cable into one of the coaxial ports on a splitter.
Disconnect the antenna's coaxial cable from the back of your television or digital converter box.
Plug the television antenna's cable into the other coaxial port on the splitter.
Plug one end of a piece of coaxial cable into the single coaxial port on the splitter.
Plug the other end of the coaxial cable into the "Antenna In" port on the back of your television or digital converter box.
Turn on your television.
Press the "Scan" or "Menu" button on your television or digital converter box's remote control.
Select "Channel Scan" to scan the channels on your television or converter box so the TV or converter box can receive any new or missing channels.
Things You'll Need
Bow tie antenna (optional)
Coaxial cable (optional)
Rescan your television or converter box's channels frequently to see if any new or missing channels are available.
You can also boost your digital TV signal reception by installing a signal booster. The signal booster is connected by unplugging your television's antenna and connecting the antenna's cable to the "Antenna" port on the signal booster. Plug one end of a piece of coaxial cable into the "Antenna Out" port on the booster. Plug the other end of the cable into the "Antenna In" port on the back of your television or digital converter box.
If you're using an antenna that has a built in amplifier, do not install a signal booster to enhance your digital TV signal reception. The over-amplified signal will damage the television/digital converter box.
