Coax cable should be secured every blank and bend radius of no more than blank.

Coax cable should be secured every blank and bend radius of no more than blank.

• A. 2 ft, 10 times
• B. 1 ft, 5 times
• C. 3 ft, 15 times
• D. 4 ft, 8 times

Answer: (A)

The main idea is to protect coax from mechanical stress while keeping signal integrity. Securing coax at regular intervals prevents movement that could pull on connectors or damage the run, and two feet is a practical spacing that gives good support without cluttering the cable path. For bends, coax must not be forced into sharp curves because tight bends can crush the dielectric, damage shielding, and alter the impedance, leading to signal loss or reflections. A common guideline is to maintain a minimum bend radius of about ten times the cable’s diameter, which minimizes microbends and preserves performance. The other options either use an impractical securing distance or propose bend radii that are too small (risking damage) or unnecessarily large, making routing harder. So securing every two feet and keeping bend radius at least ten times the diameter best protects both the cable and the signal.
