    main product photo
    Line Directional couplers divide a small portion of the signal on the trunk line (main line) to tap lines.Signal is attenuated between Input and Tap ports. Depending on the Tap value (dB value), the small portion will be passed to the tap line. Higher the value of the DB, lower the amount of signal passed to the tap line. e.g. Tap line in 12 dB tap will have lower amount of signal then the Tap line in 8 dB tap.In addition to RF signal, the power 30V-90VAC is passed from INPUT to OUTPUT AND TAPOFF ports.The difference between Tapoff and Line Directional Couplers, is while tapoff do not have Power output on tapoff ports, in Output Line directional couplers, the power is carried from input to tapoff output ports.
