Basic RF System Design

Knowing how much amplification is needed for a system is essential to
designing a successful RF distribution system. This section explains how to
calculate the losses in your system. You should provide enough amplification
to overcome all of the insertion losses of all the system components. If the
signal splits into two branches, each branch must be calculated separately.

Basic Amplified Splitter Application

Connect the CVT-15WB as shown and locate it at the main distribution point in
the house. The CVT-15WB will supply the amplified TV signal to the splitter
which may be conned to several TV locations.
