NTRODUCTION

 

The Digital SCR LNB converts the radio waves that are reflected by a satellite dish into a 
usable format and amplifies these focused signals even further while filtering out electrical 
interference  or  other  noise.  They  also  convert  the  high  frequencies  associated  with  Ku 
satellite radio waves to a lower frequency band which can be handled by receivers more 
easily. 

In contrast to a traditional LNB which sends signals over multiple lines, the Digital SCR LNB 
feeds  signals  over  a  single  coaxial  cable.  For  installers,  this  yields  ease  of  use  during 
installation. End-users are benefitted by the availability of a wider range of TV-content.
