(2AC-1.1)
What type of radio-wave propagation occurs when the signal
travels in a straight line from the transmitting antenna to the
receiving antenna?
A. Line-of-sight propagation
*
(2AC-1.2)
What path do radio waves usually follow from a transmitting
antenna to a receiving antenna at VHF and higher frequencies?
B. A straight line
*
(2AC-2.1)
What type of propagation involves radio signals that travel
along the surface of the Earth?
D. Ground-wave propagation
*
(2AC-2.2)
What is the meaning of the term ground-wave propagation?
B. Signals that travel along the surface of the earth
*
(2AC-2.3)
Two Amateur Radio stations a few miles apart and separated by a
low hill blocking their line-of-sight path are communicating on
3.725 MHz. What type of propagation is probably being used?
B. Ground wave
*
(2AC-2.4)
When compared to sky-wave propagation, what is the usual
effective range of ground-wave propagation?
A. Much smaller
*
(2AC-3.1)
What type of propagation uses radio signals refracted back to
earth by the ionosphere?
A. Sky wave
*
(2AC-3.2)
What is the meaning of the term sky-wave propagation?
B. Signals refracted by the ionosphere
*
(2AC-3.3)
What does the term skip mean?
D. Signals are refracted by the ionosphere
*
(2AC-3.4)
What is the area of weak signals between the ranges of ground
waves and the first hop called?
A. The skip zone
*
(2AC-3.5)
What is the meaning of the term skip zone?
C. An area that is is too far for ground-wave propagation, but
too close for skip propagation
*
(2AC-3.6)
What type of radio wave propagation makes it possible for
amateur stations to communicate long distances?
D. Sky-wave propagation
*
(2AC-4.1)
How long is an average sunspot cycle?
C. 11 years
*
(2AC-4.2)
What is the term used to describe the long-term variation in the
number of visible sunspots?
D. The sunspot cycle
*
(2AC-5.1)
What affect does the number of sunspots have on the maximum
usable frequency (MUF)?
A. The more sunspots there are, the higher the MUF will be
*
(2AC-5.2)
What affect does the number of sunspots have on the ionization
level in the atmosphere?
B. The more sunspots there are, the higher the ionization level
will be
*
(2AC-6.1)
Why can a VHF or UHF radio signal that is transmitted toward a
mountain often be received at some distant point in a different
direction?
C. These radio signals are easily reflected by objects in their
path
*
(2AC-6.2)
Why can the direction that a VHF or UHF radio signal is
traveling be changed if there is a tall building in the way?
C. These radio signals are easily reflected by objects in their
path
