1. What is the primary function of a satellite dish?
A. Amplify internet speed
B. Transmit and receive signals from satellites
C. Store digital data
D. Generate electrical power
Rationale: A satellite dish is designed to receive and send
signals to satellites in orbit for communication services.
Correct Answer: B. Transmit and receive signals from satellites
2. Which frequency band is commonly used for satellite TV
broadcasting?
A. VHF
B. UHF
C. Ku-band
D. AM band
Rationale: Ku-band frequencies are widely used for satellite
television due to efficient bandwidth and signal clarity.
Correct Answer: C. Ku-band
,3. What device converts satellite signals into usable television
signals?
A. Modem
B. LNB (Low Noise Block Downconverter)
C. Router
D. Amplifier
Rationale: The LNB receives microwave signals and converts
them into lower frequency signals for the receiver.
Correct Answer: B. LNB (Low Noise Block Downconverter)
4. What is the purpose of aligning a satellite dish?
A. To increase internet data usage
B. To ensure proper signal reception from a satellite
C. To reduce electricity consumption
D. To encrypt data transmission
Rationale: Proper alignment ensures the dish is directly facing
the satellite for optimal signal strength.
Correct Answer: B. To ensure proper signal reception from a
satellite
5. What tool is commonly used to measure satellite signal
strength during installation?
,A. Voltmeter
B. Spectrum analyzer or signal meter
C. Thermometer
D. Oscilloscope
Rationale: Signal meters help technicians fine-tune dish
alignment by measuring signal quality.
Correct Answer: B. Spectrum analyzer or signal meter
6. What is polarization in satellite communication?
A. Power supply type
B. Direction of electromagnetic wave orientation
C. Weather interference level
D. Cable resistance type
Rationale: Polarization refers to the orientation of the signal
wave, important for proper reception.
Correct Answer: B. Direction of electromagnetic wave
orientation
7. What is the main role of a satellite receiver (set-top box)?
A. Generate satellite signals
B. Decode and display satellite TV content
C. Increase dish size
D. Block interference
, Rationale: The receiver decodes the signal from the LNB into
viewable audio/video content.
Correct Answer: B. Decode and display satellite TV content
8. What causes most satellite signal loss?
A. Strong internet connection
B. Atmospheric conditions like heavy rain
C. High battery power
D. Cable color
Rationale: Rain fade and weather conditions can significantly
weaken satellite signals.
Correct Answer: B. Atmospheric conditions like heavy rain
9. What does “line of sight” mean in satellite installation?
A. Direct cable connection
B. Unobstructed path between dish and satellite
C. Wireless internet path
D. Electrical grounding system
Rationale: Satellites require a clear path without physical
obstructions.
Correct Answer: B. Unobstructed path between dish and
satellite
