  1. Which tool is used to verify that a satellite dish is correctly aimed in azimuth and elevation during installation?

    Answer: Spectrum analyzer with satellite signal meter

    A spectrum analyzer or satellite signal meter displays signal strength and quality in real time, allowing precise azimuth and elevation adjustment.

  2. What is the purpose of a diplexer used in satellite dish installations?

    Answer: Combine or separate satellite and off-air antenna signals on a single coax

    A diplexer allows satellite IF signals and off-air (UHF/VHF) signals to share a single coaxial cable run without interference.

  3. When installing a satellite dish on a non-penetrating roof mount (NPRM), what is the primary structural concern?

    Answer: Wind load calculations and ballast weight requirements

    NPRMs rely entirely on ballast weight to resist wind uplift, so correct calculation of wind load and required ballast is critical for safety.

  4. What is the standard intermediate frequency (IF) range output from an LNB to the satellite receiver?

    Answer: 950–2150 MHz

    LNBs downconvert satellite signals to the 950–2150 MHz IF range, which can be transmitted over standard RG-6 coaxial cable to the receiver.

  5. During a satellite dish installation, a technician measures the signal-to-noise ratio (SNR). What does a low SNR indicate?

    Answer: There is excessive noise relative to the desired signal

    A low SNR means the noise floor is high relative to the satellite signal, typically caused by misalignment, obstructions, or faulty equipment.

  6. Which OSHA regulation most directly governs ladder safety requirements for satellite installation technicians working on residential rooftops?

    Answer: 29 CFR 1926.1053

    29 CFR 1926.1053 covers ladder safety requirements for the construction industry, including proper angle, securing, and load ratings applicable to rooftop work.

  7. What is the correct procedure when a satellite technician discovers an existing grounding electrode conductor that appears undersized?

    Answer: Upsize it to meet current NEC 810 requirements before connecting

    Before bonding new equipment, any undersized grounding conductor should be replaced to meet NEC 810 minimums to ensure adequate protection.
