After a crushed coax jumper on a city-yard AP, VSWR/return-loss measurements worsen and radiated performance drops. What does the expert recognize?
Select an answer to reveal the explanation.
Short Explanation
A crushed jumper is a kinked garden hose for RF — energy reflects instead of radiating, and VSWR/return loss tell on it. That's an antenna-system fault, not a password or DNS mystery. MU-MIMO won't unkink coax.
Full Explanation
VSWR and return loss characterize impedance match in the antenna feed system. Damage such as a crushed jumper increases reflected power, raising VSWR and reducing energy delivered to free space. This is an RF hardware fault distinct from SSID credentials, DNS, or MU-MIMO features.
