1. Which type of satellite orbit is most commonly used for direct
broadcast television?
A. Low Earth Orbit (LEO)
B. Medium Earth Orbit (MEO)
C. Geostationary Earth Orbit (GEO)
D. Polar Orbit
Rationale: Geostationary satellites maintain a fixed position
relative to the Earth's surface, making them ideal for continuous
broadcast services like television.
2. What is the primary purpose of a satellite LNB (Low-Noise Block
downconverter)?
A. To transmit signals to the satellite
, B. To receive high-frequency signals from the satellite and
convert them to a lower frequency
C. To amplify the TV signal inside the home
D. To steer the dish toward the satellite
Rationale: The LNB converts the high-frequency microwave
signals from the satellite into a lower frequency suitable for
coaxial cable transmission.
3. Which unit measures the strength of a received satellite signal?
A. Decibels (dB)
B. Ohms
C. dBm (decibels relative to 1 milliwatt)
D. Hertz (Hz)
Rationale: Satellite signal strength is measured in dBm to
quantify the power level of the received microwave signal.
4. What is the typical frequency range for Ku-band satellite signals?
A. 1–2 GHz
B. 4–6 GHz
C. 12–18 GHz
D. 20–30 GHz
Rationale: Ku-band frequencies typically range from 12 to 18
GHz and are widely used for satellite TV and VSAT services.
,5. When aligning a satellite dish, which two angles are critical?
A. Roll and yaw
B. Azimuth and roll
C. Azimuth and elevation
D. Pitch and tilt
Rationale: Proper alignment requires setting the azimuth
(horizontal direction) and elevation (vertical angle) to point
accurately at the satellite.
6. What is the main advantage of using a motorized satellite dish?
A. Lower installation cost
B. Better signal quality without alignment
C. Ability to track multiple satellites without reinstallation
D. Reduced cable length
Rationale: Motorized dishes can rotate to different satellites,
allowing one dish to receive signals from multiple orbital
positions.
7. Which of the following can cause rain fade in satellite
communications?
A. Fog
B. Heavy rainfall
C. Wind
, D. Snow
Rationale: Rain absorbs and scatters microwave signals,
especially in Ku and Ka bands, reducing signal quality—a
phenomenon called rain fade.
8. What type of coaxial cable is most commonly used for satellite
installations?
A. RG-58
B. RG-6 Quad-shield
C. RG-6
D. RG-11
Rationale: RG-6 is standard for satellite installations due to its
low loss and shielding, while RG-6 Quad-shield is used in high-
interference areas.
9. Which polarization types are typically used in satellite signals?
A. Horizontal only
B. Vertical only
C. Horizontal and Vertical
D. Circular only
Rationale: Satellites use both horizontal and vertical polarization
to allow frequency reuse and reduce interference.
