1. What is the primary purpose of proper antenna and line
installation on a telecommunications structure?
A. To improve tower aesthetics
B. To maximize signal propagation and ensure structural safety
C. To reduce labor costs
D. To eliminate grounding requirements
Answer: B
Rationale: Proper antenna and transmission line installation
ensures optimal RF signal performance while maintaining
structural integrity and safety compliance. Aesthetic
improvements and cost reduction are secondary considerations.
2. What document typically provides antenna mounting
specifications and torque values?
, A. OSHA handbook
B. Manufacturer’s installation manual
C. Site lease agreement
D. FCC license
Answer: B
Rationale: The manufacturer’s installation manual provides
detailed mounting requirements, torque specifications, and
alignment instructions critical for safe and compliant installation.
3. What is the primary function of a coaxial transmission line?
A. To provide structural support
B. To transmit RF energy from radio to antenna
C. To ground the tower
D. To cool the antenna
Answer: B
Rationale: Coaxial transmission lines are designed to carry RF
energy efficiently from the transmitter to the antenna with
minimal signal loss.
4. What is VSWR primarily used to measure?
A. Voltage supply rating
B. Weather resistance
C. Signal reflection and mismatch
, D. Vertical support weight rating
Answer: C
Rationale: Voltage Standing Wave Ratio (VSWR) measures
reflected power caused by impedance mismatch, indicating
transmission line and antenna efficiency.
5. Which component protects RF connectors from moisture
intrusion?
A. Galvanized bolts
B. Weatherproofing tape and mastic
C. Structural sleeves
D. Cable ties only
Answer: B
Rationale: Weatherproofing tape and mastic seal connectors
against moisture, preventing corrosion and signal degradation.
6. Proper torque application on antenna mounts prevents:
A. Overheating
B. Structural failure and loosening
C. RF interference
D. Signal amplification
Answer: B
, Rationale: Applying proper torque ensures structural stability and
prevents loosening due to vibration or wind loading.
7. What is the minimum approach distance primarily designed to
prevent?
A. Signal overlap
B. Electrical contact and RF overexposure
C. Equipment theft
D. Ice accumulation
Answer: B
Rationale: Minimum approach distances protect workers from
energized components and excessive RF exposure.
8. What is the function of a hybrid coupler in antenna systems?
A. Structural reinforcement
B. Combining or splitting RF signals
C. Lightning grounding
D. Weather sealing
Answer: B
Rationale: Hybrid couplers combine or split RF signals while
maintaining impedance balance.
9. A sweep test is used to detect:
A. Structural cracks
