this chapter). You can also patch rf and audio from one compartment to another. A frequency standard is
connected (through a distribution amplifier not shown) to the receivers.
Figure 3-12.—Complex distribution system.
Transmitting antenna distribution systems perform the same functions as receiving systems.
However, because of the higher power levels, design and fabrication problems are more difficult. The
ideal design would be to have all the transmission lines designed for the highest power level. But because
high-power patch cords are expensive, large, and difficult to handle, this approach is seldom followed.
In practice, the basic patch panel we just looked at in figure 3-11 is practical for low power levels.
Another type of transmitter patch panel is shown in figure 3-13.
