SBCA Installation Practices & Standards 2

Question 1

What is the minimum recommended torque for N-type connector installation on RG-6 coaxial cable?

Accepted Answer

12 in-lb

Answer

N-type connectors on RG-6 should be torqued to approximately 12 in-lb to ensure a weatherproof, low-loss connection.

Question 2

When bonding a satellite dish mounting pole to the grounding system, which conductor size is required by NEC 810?

Accepted Answer

6 AWG copper

Answer

NEC Article 810 requires a minimum 10 AWG copper or 6 AWG aluminum bonding conductor, but 6 AWG copper is the most commonly specified for satellite installations.

Question 3

What is the maximum recommended bend radius for RG-6 quad-shield coaxial cable during installation?

Accepted Answer

3 inches

Answer

RG-6 quad-shield cable should not be bent tighter than a 3-inch radius to avoid impedance changes and signal degradation.

Question 4

Which type of grounding electrode is preferred for satellite dish installations when no existing grounding system is present?

Accepted Answer

Ground rod driven 8 feet deep

Answer

An 8-foot copper-clad ground rod driven into the earth provides a dedicated, reliable grounding electrode when no existing system is available.

Question 5

When running coaxial cable through an exterior wall, which sealing method best prevents water infiltration?

Accepted Answer

Self-amalgamating (self-fusing) silicone tape

Answer

Self-amalgamating silicone tape creates a waterproof, UV-resistant seal around cable penetrations that won't dry out or crack over time.
