Functional Description
For each configuration (HH, HS, NS, FF, NN), the RF Distribution routes signals
differently.
In the hot-standby (HH) configuration waveguide routes signals from both transmitters to
a common antenna, and from the antenna to both receivers as Figure 3-2-1 shows.
For all configurations, transmitter output goes through coaxial cable to a transmit filter,
and the received signal from the antenna goes from the Rx filter through coax to the
receiver.
In hot-standby transmit/space diversity receive (HS) configurations waveguide routes
signals from both transmitters and primary receiver to and from a common antenna. A
secondary receiver connects to the diversity antenna as Figure 3-2-2 shows.
