The DIP1 splitting diplexer is normally used indoors to separate satellite and TV. It employs high isolation filters to prevent interference between the satellite and TV. The satellite DC is fed through the Diplexer to the combining diplexer dip1, dip2, dip2-dc. - Allows a Satellite signal to be added to an existing system - High isolation between Satellite and TV ports - Low insertion Loss TV Port: 47-860MHz Insertion Loss: <2dB Isolation: >40dB Current Passed to UHF/VHF Port: 0 Impedance: 50ohms Satellite Port: 950 -2150MHz Insertion Loss: <3dB Isolation: 30dB Current Passed: A max External Installation: No
