The C-0300 is a return path amplifier that provides 15dB of gain in the
frequency range between 5-42 MHz. While many amplifiers are “Bidirectional” they typically allow signals to pass back to the cable company
without amplifying them. In some cases this is not a problem, but in
larger systems, the insertion loss of splitters may prevent signals which
are transmitted by your interactive cable box from returning to the cable
company. This problem may prevent your cable box from working
properly. The C-0300 works to supplement an existing distribution
system. It only amplifies signals in the return path and allows signals in
the forward direction to pass through with minimal attenuation.
Features:
!
15dB gain from 5-42MHz (return path)
!
<1 dB attenuation from 54MHz-1,000MHz
!
Works with existing amplifiers that have a passive return path

The C-0300 provides enough return path gain to compensate for the
loss created by a typical 16-way RF splitter. Without it, large RF
distribution systems may experience problems when using interactive
cable boxes.
