TV Antenna/Video Signal Combiner
(150-1299)                 Connections                Faxback Doc. # 18216

To connect a Channel 3 or 4 video source, you need two 75-Ohm coaxial 
cables with F-connectors at each end. 

If your TV's connector is a 300-Ohm type, you can use a 300-Ohm to 75-Ohm 
adapter for connection. 

You can buy both coaxial cables and adapters at your local Radio Shack  
store. 

1.  Connect the output from your video source (cable TV converter,
    satellite TV, VCR, or video disc player) to CH3 IN (for 15-1298) or CH4
    IN (FOR 15-1299) on the back of the signal combiner. 

    NOTE:  Be sure to set your video source's output to the channel that 
           matches your signal combiner's input (Channel 3 for 15-1298; 
           Channel 4 for 15-1299). 

2.  Connect the signal combiner's TO TV connector to your TV's antenna 
    input terminal. 

3.  Connect the antenna's cable to the signal combiner's ANT IN connector. 

NOTE:  You can use a video splitter/combiner (available at your local Radio
       Shack store) to split the signal combiner's output and send the
       combined signals throughout your home.  This lets you select either
       the TV antenna or video source from more than one television. 

Use only as much RG-6 coax cable as is necessary to reach each TV. 

Adjustment

If there is a broadcast station on Channel 3 (15-1298) or Channel 4 
(15-1299), video and broadcast signals can interfere with the video
signal's picture.  Follow these steps to balance signals to eliminate this
interference. 

1.  Turn on your TV and the video input source. 

2.  Tune the TV to Channel 3 (15-1298) or Channel 4 (15-1299). 

3.  Remove the plugs from the ANT ADJ and CH3 ADJ or CH4 ADJ controls. 
    Adjust ANT ADJ for the best picture, then adjust CH3 ADJ or CH4 ADJ 
    until the interference disappears.
