← ScienceWhich risk increases significantly when voltage standing-wave ratio rises on transmission cabling?
A)Premature magnetron tube failure✓
B)Increased antenna array beamwidth
C)Signal phase distortion lessens
D)Lowered receiver sensitivity occurs
💡 Explanation
High VSWR causes increased power reflections back towards the source, because of impedance mismatches in the line; therefore, magnetron back-heating rises and tube lifespan shortens, rather than changes to antenna properties or signal fidelity downstream.
