Figure 13. AT-984A/G radiation pattern.
PRACTICE EXERCISES:
21. In highly mobile tactical operations, a vertically mounted receiving
antenna is better than a horizontally mounted antenna, because--
a.
it
is horizontally polarized.
b.
it
can receive signals from all directions.
c.
it
is less susceptible to jamming.
d.
it
is directional.
22. You have just chosen a wide clearing in the woods for
a
radio
transmitter site. You should locate your radio antenna--
a.
on the edge nearest the most distant station.
b.
on the edge farthest from the distant station.
c.
inside the tree line to conceal the antenna system.
d.
on the edge nearest the receiving radio set to reduce the length of
the transmission line.
23. Antenna AT-984A/G is a long-wire, directional antenna used to increase
the range of FM radios operating in the frequency range of--
a.
20.00
to
27.00
MHz.
b.
20.00
to
72.00
MHz.
c.
30.00
to
76.00
MHz.
d.
53.00
to
76.00
MHz.
