  1. What is the recommended spacing between cable staples or clips when securing RG-6 coaxial cable along an exterior wall?

    Answer: 24 inches

    SBCA and most manufacturer guidelines recommend securing RG-6 coax every 24 inches on exterior runs to prevent sagging and wind damage.

  2. When a multiswitch is used in a satellite distribution system, what does it require from the dish LNB port?

    Answer: Dual or quad LNB outputs providing all orbital positions and polarities

    A multiswitch requires separate LNB outputs carrying different polarities and, in multi-satellite systems, different orbital positions to distribute all channels independently.

  3. Which standard governs the structural wind load requirements for satellite dish mounting hardware in the United States?

    Answer: TIA-222

    TIA-222 (Structural Standard for Antenna Supporting Structures and Antennas) governs wind load and structural requirements for antenna mounts.

  4. A satellite receiver displays 'searching for signal' after installation. After confirming dish alignment, what is the next most logical troubleshooting step?

    Answer: Check the coaxial connection at the LNB and receiver for proper seating and continuity

    Loose or corroded coaxial connections are among the most common causes of signal loss and should be verified before replacing components.

  5. What is the purpose of applying dielectric grease to outdoor F-connector threads during installation?

    Answer: Prevent corrosion and moisture ingress at the connection point

    Dielectric grease creates a moisture barrier at the connector threads, preventing corrosion that would increase insertion loss over time.

  6. When installing a satellite dish on a chimney mount, what is the minimum clearance required between the dish and the top of the chimney?

    Answer: 12 inches

    A minimum 12-inch clearance above the chimney top is required to avoid signal interference from chimney gases and to meet safety codes.

  7. In a satellite installation, what is the function of the 22 kHz tone signal sent by the receiver to the LNB?

    Answer: Switch between high and low band on a universal LNB

    A 22 kHz tone sent from the receiver switches a universal LNB between its low local oscillator (LO) frequency for low band and high LO for high band reception.
