hoisted to the nearest structure and secured. The end
with the alligator clip (or lug) is attached to the
equipment transmission line. To radiate effectively, the
antenna must be sufficiently clear of all grounded
objects.
ANTENNA DISTRIBUTION
SYSTEMS
In figure 2-36, we see a distribution system with one
antenna that can be connected (patched) to one of
several receivers or transmitters by way of a
multicoupler. In this system, you can patch the antenna
to only one receiver or transmitter at a time. However,
some distribution systems are more complex, such as
the one shown in figure 2-37. In this system, you can
patch four antennas to four receivers, or you can patch
one antenna to more than one receiver via the
multicoupler. In either system, we need a way to
connect the antenna to the receiver or transmitter that
we want to use.
