← ScienceConsider a municipal coax cable network. Which consequence results when water breaches a cable jacket?
A)Increased signal attenuation with frequency✓
B)Reduced characteristic impedance of cable
C)Elevated reflected power at source
D)Decreased cable capacitance per meter
💡 Explanation
Water intrusion causes dialectric losses which become greater with frequency. Increasing signal *attenuation* across the cable *increases.* The mechanism at work here is *dielectric absorption* because water molecules impede correct propagation; therefore attenuation is higher, rather than an impedance/reflection effect.
