SUBELEMENT T3 – RADIO WAVE PROPAGATION – [3 Exam Questions – 3 Groups] 34 Questions
T3A – Radio wave characteristics: how a radio signal travels, fading, multipath, polarization, wavelength vs absorption; Antenna orientation
T3A01
Why do VHF signal strengths sometimes vary greatly when the antenna is moved only a few feet?
A. The signal path encounters different concentrations of water vapor
B. VHF ionospheric propagation is very sensitive to path length
C. Multipath propagation cancels or reinforces signals
D. All these choices are correct
T3A01 asks why VHF signal strengths sometimes vary greatly when the antenna is moved only a few feet. The correct answer is:
C. Multipath propagation cancels or reinforces signals
When the antenna is moved even a few feet, the signal can encounter different paths due to reflections from buildings, trees, or the ground. These multiple signal paths can interfere with each other, causing variations in signal strength at different locations. This phenomenon is known as multipath propagation, where signals can cancel each other out or reinforce each other, leading to varying signal strengths.
T3A02
What is the effect of vegetation on UHF and microwave signals?
A. Knife-edge diffraction
B. Absorption
C. Amplification
D. Polarization rotation
T3A03
What antenna polarization is normally used for long-distance CW and SSB contacts on the VHF and UHF bands?
A. Right-hand circular
B. Left-hand circular
C. Horizontal
D. Vertical
T3A03 discusses the antenna polarization typically used for long-distance CW and SSB contacts on the VHF and UHF bands. The correct answer is:
D. Vertical
For long-distance CW (Continuous Wave) and SSB (Single Sideband) contacts on the VHF and UHF bands, vertical antenna polarization is commonly used. This orientation helps maximize signal propagation efficiency for these types of communications.
T3A04 (B)
What happens when antennas at opposite ends of a VHF or UHF line of sight radio link are not using the same polarization?
A. The modulation sidebands might become inverted
B. Received signal strength is reduced
C. Signals have an echo effect
D. Nothing significant will happen
In question T3A04, when antennas at opposite ends of a VHF or UHF line of sight radio link are not using the same polarization, the correct answer is:
B. Received signal strength is reduced
Mismatched polarizations between transmitting and receiving antennas can lead to a reduction in received signal strength due to polarization losses, thereby affecting the quality and reliability of the communication link.
T3A05
When using a directional antenna, how might your station be able to communicate with a distant repeater if buildings or obstructions are blocking the direct line of sight path?
A. Change from vertical to horizontal polarization
B. Try to find a path that reflects signals to the repeater
C. Try the long path
D. Increase the antenna SWR
In question T3A05, if buildings or obstructions are blocking the direct line of sight path when using a directional antenna to communicate with a distant repeater, the following approach can be used:

B. Interference from thunderstorms
C. Intermodulation distortion
D. Random combining of signals arriving via different paths
In question T3A08, a likely cause of irregular fading of signals propagated by the ionosphere is:
D. Random combining of signals arriving via different paths
Irregular fading of signals from the ionosphere can occur due to the random combining of signals arriving via different paths, leading to variations in signal strength and quality.

B. Transmission rates must be decreased by a factor equal to the number of separate paths observed
C. No significant changes will occur if the signals are transmitted using FM
D. Error rates are likely to increase
In question T3A10, the effect multi-path propagation has on data transmissions is:

T5C09
How much power is delivered by a voltage of 13.8 volts DC and a current of 10 amperes?
A. 138 watts
B. 0.7 watts
C. 23.8 watts
D. 3.8 watts
T5C10
How much power is delivered by a voltage of 12 volts DC and a current of 2.5 amperes?
A. 4.8 watts
B. 30 watts
C. 14.5 watts
D. 0.208 watts
T5C11
How much current is required to deliver 120 watts at a voltage of 12 volts DC?
A. 0.1 amperes
B. 10 amperes
C. 12 amperes
D. 132 amperes
To calculate the current (I) required to deliver 120 watts at a voltage of 12 volts DC, you can use the formula:
P = I x E Therefore P/E=I
Given:
- Power (P) = 120 watts
- Voltage (V) = 12 volts
120watts / 12 volts volts = 10 amperes
T5C12
What is impedance?
A. The opposition to AC current flow
B. The inverse of resistance
