SBCA Installation Practices & Standards 4

Question 1

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

Accepted Answer

24 inches

Answer

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

Question 2

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

Accepted Answer

Dual or quad LNB outputs providing all orbital positions and polarities

Answer

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

Question 3

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

Accepted Answer

TIA-222

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

Prevent corrosion and moisture ingress at the connection point

Answer

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