DIRECTIONAL COUPLER & POWER INSERTOR

DIRECTIONAL COUPLER & POWER INSERTOR.  
                
                                                 
■ APPLICATION
 • This device is to distribute the trunk line without the valation of impedance in CATV transmitting system.
 
 FEATURE 
 • The flatness of transmission and reflection is low.
 • Since it is Diecasting case, it shields RFI and EMI excellently
    and it has a excellent waterproofing function and durability.
 • Since the surface is coated, it is incorrodible and doesn't fade easily.
 • It can transmit with RF signal to the place where needs
    the AC power of coaxial cable and also breaking is available.

■ APPLICATION
 • This is a mixing and generating device of RF signal and
    AC power with the element which supplies the AC power that
    was supplied from generator to transmission cable.
