There are two main principles for TV signal routing for several consumers: pa-
rallel diagram, or routing by “star” and sequential diagram.
The first case uses signal distribution connectors (also called dividers or split-
ters). The input signal power is divided equally into 2, 3, 4, but each time the
signal is split into 2, the signal power at each output is also reduced by half (in
fact, it is a bit more than half — the reduced signal is usually 3,5–4.5 dB). This
method of routing ensures a high degree of power uniformity in the TV frequen-
cy band and a high degree of isolation between the outputs, however it requi-
res more cable. In the second case couplers (tappers) and TV outlets appear as
connected cascading one by one. This method of routing gives unequal signal
distribution. It is easier to install and requires less cable. However, this diagram
can be used to route the signal to a lower number of consumers.
