How do I connect my analog TV and antenna with a digital converter box?:


After determining if the TV is a digital TV or an analog TV, the equipment needed depends on whether the TV supports multiple input sources. To determine if the TV supports multiple input sources, look at the back of the TV.

  • If the TV accepts multiple input sources, you may see a variety of red, yellow, black, and other input connectors located near where you would connect your TV cable or antenna. You will also want to determine if your TV is a Digital TV by consulting the owner’s manual.
  • If the TV does not support multiple input sources, an A/B switch will allow you to switch between the cable and antenna connection quickly and easily.
  • If the TV is not a digital TV, you will also need a digital converter box to convert the digital signals to a format the TV can display.
Analog TV - Connect both the Digital converter and Antenna
  1. Power off your TV.
  2. Connect the antenna to the RF or Antenna connection on your digital converter box. Connect the output of the digital converter box to the RF or Antenna connection on your TV. Be sure the connections are hand-tight.
  3. Place your antenna in an area where walls or other objects cannot block the reception.
  4. Turn on your TV and follow your television’s user guide to set up your antenna connection.
  5. When you want to watch local programming using the antenna connection, go to your TV’s input menu, and select the antenna connection you set up in Step 4. When you want to return to watching cable channels, go to the menu and select your cable connection.
  6. Adjust the antenna until you receive the clearest picture. Remember, these are over-the-air transmissions. Many factors, including weather, can affect your reception.
Analog TV - Antenna with A/B Switch
  1. Power off your TV.
  2. Connect the incoming TWC coaxial cable to one of the input connections on the A/B switch.
  3. Connect the antenna to the other input connection on the A/B switch.
  4. Using a separate piece of coaxial cable, connect the output of the A/B switch to the input of the digital converter box. Then connect a second piece of coaxial cable from the digital converter box to the RF/Antenna input on the back of the television.
  5. Turn on your TV and place the antenna in an area where walls or other objects cannot block the reception.
  6. Using the control switch on the A/B switch, change your input from A to B and vice versa. If your cable is connected to the “A” input on your A/B switch, you will receive your cable channels when the control switch is turned to the “A” position. If your antenna is connected to the “B” input on your A/B switch, you will receive your antenna channel when the control switched is turned to the “B” position.
  7. Adjust the antenna until you receive the clearest picture. Remember, these are over-the-air transmissions and many factors, including weather, can affect your reception.
